The proportion of recycled plastic is fairly high compared with that in other EU-countries, but ambitions are high, particularly against the background of the new tough recycling demands which come into force in 2020. In order to make the cyclic process more effective, a joint language is required, a standard for the recycling of plastic. The Swedish Standards Institute, SIS, has accepted the challenge and Professor Antal Boldizar is a member of the expert group.</b></p>Plastics are complex and controversial materials from an environmental perspective. A broad range of plastic materials are used in the manufacturing industry, since they are relatively resource-efficient, design-friendly and light in weight, but there are disadvantages in that they are based on fossil-fuels and degrade very slowly, and garbage sorting at source is an important first step towards the achievement of a cyclic system in which plastics can be re-used for new purposes. <br /><br /><img src="/SiteCollectionImages/Institutioner/IMS/Konstruktionsmaterial/300x200-plastskrap.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px 10px" />Chalmers has a strong competence in this field, in for example Antal Boldizar, Professor in the Department of Industrial and <span></span>Materials Science, whose work focuses on environment-adapted polymeric structural materials.  He is leader of a Polymeric Materials and Composites research group devoted to the study of the relationships between the structure, processing and functional properties of polymeric materials, such as polymeric composites reinforced with cellulose fibres. The recycling of plastics and the use of bio-plastics are other strong fields. <br /><br /><strong>Sweden takes the lead in developing a new joint Standard </strong><br />Now that Sweden through SIS is taking a joint initiative with regard to the future sustainable use of plastics, Antal is one of the experts in the group which will work on the terminology and standardization of recycled plastics.<br />”I‘m looking forward to it.  It is an important field for both society and industry.  One can say that standardization is the industrial language”, says Antal, and continues: “there is a great need for a clear terminology.  Many new concepts are used indistinctly and the industry requires greater clarity with regard to terminology and standards.”<br /><img src="/SiteCollectionImages/Institutioner/IMS/Konstruktionsmaterial/Johan%20Dahlgren%20SIS.png" class="chalmersPosition-FloatRight" alt="" style="margin:5px 10px;width:169px;height:165px" /><br />Johan Dahlgren (to the right), the project leader at SIS, agrees.<br />”We are working to develop clearer definitions relating to plastics in a cyclic economy.  It is important that all the actors in the value-chain use the same terminology, in order for example to be able to compare and evaluate results.  A Standard can be seen as a joint solution of a recurrent problem.  It is in everyone’s interest to raise quality, to avoid misunderstanding and to avoid reinventing the wheel every time.” <br /><br /><strong>Many different perspectives are required</strong><br />Johan Dahlgren says further that a major task of the working group is to contribute to the future sustainable use of plastics. A key feature is the recycling of plastics, but bio-plastics are also an interesting field.<br />”Standardization is often applied research strongly linked to the work of academia. Unfortunately, universities and colleges are not always able to participate in the SIS committees because of the participation fees”, says Johan Dahlgren, ”but at the same time it is important that as many perspectives as possible are represented to ensure that the Standards are good. It is therefore valuable that Antal Boldizar is able to contribute with his knowledge and opinions from his research perspective.”        <br />   <br /><strong>Recycled plastic from electronic waste </strong><br />It normally takes between 18 months and three years to develop a Standard. The first step is to clarify the need for standardization in a given sector and that report is expected to be available by the end of 2019.   What questions are important now at the start?<br />”About 40 % of the plastics used in Sweden is now being recycled,” says Antal, “a large and readily available part of the recycled plastic in Sweden comes from industrial spillage, i.e. waste from the manufacturing process.  There is a good reason for this – the material has not been contaminated or aged.  It is in effect a new material with known properties easy to use in a manufacturing process.”<br />“But how much of the plastic recovered from old materials can be reused?” asks Antal and continues, ”a couple of years ago we had <a href="" target="_blank">a successful project </a>where Erik Stenvall, a doctoral student with us, studied plastic components recovered from electronic waste and showed that 100 % can be reused, but that the process parameters need to differ considerably from those used in the processing of new material.”<br />“Now, I hope to be able to contribute to the development of a clearer picture of the technical potential of recycled material, and the functional properties which can be achieved through e.g. suitable melt-processing.  In this context, we are especially interested in cooperation with the industry, in order to be able better to work with processes on a large scale” finishes Antal Boldizar.<br /><br /><span lang="en"><a href="/en/Staff/Pages/antal-boldizar.aspx" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" /><span>Read more about Antal Boldizar</span></a><br /><a href="" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" /><span>Recycled plastic from electronics scrap</span></a><br /></span><a href="" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" /><span lang="en"><span>Read more about SIS</span></span></a><br /><br /><span class="short_text" lang="en"><span><strong>FACTS - SIS group for environmental aspects of plastic</strong></span></span><span lang="en"><span><br />The group influences content for new standards such as CEN and ISO, and develops a basis for new standards (eg test methods, processes, terminology, classifications).<br /><span></span><strong>Participants: </strong>Avfall Sverige, Borealis, Chalmers, Electrolux, Fortum Waste Solutions, Håll Sverige Rent, IKEM, Mondi, Naturskyddsföreningen, Perstorp, Ragn-Sells, RISE, SIS, SPIF, Swerea IVF, Tetra Pak, and Trioplast.<br /><br /><em>Text: Carina Schultz</em><br /><em>Översättning: J Anthony Bristow</em><br /><em>Photo: Sten Jansin (portrait Johan Dahlgren) and Carina Schultz</em><br /></span></span><br />Fri, 10 Aug 2018 00:00:00 +0200 the quest for high-entropy alloys that survive 1500 °C<p><b>​An aero-engine should operate at the highest possible temperature for the best output power and energy efficiency.

The materials and manufacture researcher Saad Sheikh focuses on developing HEAs with optimum tensile ductility and strength, superior than the current state-of-the-art nickel based superalloys. </span><div><br /><span style="background-color:initial"></span><div>This work is driven by the need to improve the energy efficiency of aerospace and power-generation gas-turbine engines. For example, if cooling of aero-engines can be avoided, the aero-engine output power and energy efficiency would increase up to 50%. Other applications like solar power, fuel cells, materials processing and petro-chemistry can also benefit from the results. </div> <div><br /></div> <div><strong>The aim is to be able to operate engines at higher temperatures </strong>than today. Today’s engines expose the nickel based superalloys inside to temperatures approaching 1200 °C, which is close to 90% of their melting points. In the hottest region of a turbine engine, temperatures are approaching 1500 °C. By using complex cooling systems and coatings the nickel based superalloys can exist in the hottest region but the efficiency gained from operating at higher temperatures is greatly reduced, as the cooling needs extra work.</div> <div><img src="/SiteCollectionImages/Institutioner/IMS/Material%20och%20tillverkning/Saad-Sheikh_250pxl.jpg" alt="Saad Sheikh" class="chalmersPosition-FloatLeft" style="margin:5px" /><br /><span style="background-color:initial;font-family:calibri, sans-serif;font-size:11pt">– </span><span style="background-color:initial">The current situation of higher inefficiency losses is alarming, but also provides opportunity to look for new ground-breaking materials.

Four students from four different master programs were appointed as the pioneering research associates in this seed-bed programme. Having just presented their research results, what did the students think about the programme?</b></p><div>Inspired by US universities, <a href="/en/areas-of-advance/production/Pages/default.aspx">the Production Area of Advance</a> earlier this year launched a new Research Associate Programme to enable talented students from the master programs to obtain some experience from research activities. In the first round, four project applications by students from four different master programs was granted. </div> <div><br /></div> <div><a href="/en/areas-of-advance/production/news/Pages/Seed-bed-for-future-production-researchers.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Read more about the programme and the pioneering projects in the first article: Seed-bed for future production researchers</a></div> <div><br /></div> <div>The projects have been reported mid-term and the final reports have recently been held. We are now curious to hear how the students have experienced this period as researchers. <strong>Priska Herzog</strong> is the first to answer and she starts with the very beginning.</div> <div><br /></div> <div>“It was nice to be able to choose ourselves what we wanted to do”, says Priska Herzog.</div> <div><br /></div> <div>She decided on a project connected to her burning interest in sports. The project was about involving sports technology in product development with the aim to improve the offering of sports projects for students. <span style="background-color:initial">Priska did a survey among her fellow students to investigate the interest for sports related studies. The result was very positive and Priska now recommends Chalmers to motivate lecturers to use sports technology in courses. As for trying out as a researcher, she made an observation during the project. </span></div> <div><span style="background-color:initial"><br /></span></div> <div>“It was good to have a project to refer to when contacting professors. It was easier to get their attention than usual”, says Priska. On that comment, the other students nods and <strong>Adis Imsirovic</strong> says:</div> <div><br /></div> <div>“I got good help from my mentor MariAnne (professor MariAnne Karlsson, editor’s note) to narrow the scope of my research”. </div> <div><br /></div> <div>In Adis project he wanted to compare the view of design between Scandinavian and Balkan designers and based his research on several interviews with both academic and industrial representatives in Sweden and Bosnia-Herzegovina. At the beginning of the project he got a bit overwhelmed about the task. </div> <div><br /></div> <div>“It would have been nice to have an introduction to research work in the beginning, in order to get a good start”, says Adis and continues “the research turned out to be a lot more work than expected”. </div> <div><br /></div> <div>During the project accounts, Adis Imsirovic presented a thick research report and <a href="/en/staff/Pages/johan-malmqvist.aspx">Professor Johan Malmqvist</a>, who is responsible for the Research Associate Programme, suggested that Adis should use the report as a basis and submit it to a scientific conference. Being a student with a published scientific article in his CV would be unusual and a benefit to him. By publishing the material, all Adis hard work during the spring would provide him additional bonus effects.</div> <div><br /></div> <div>Also <a href="/en/staff/Pages/melanie-despeisse.aspx">Assistant Professor Mélanie Despeisse</a> thought that publishing the student’s results would be a good idea. Her protégé <strong>Hasnain Thathia</strong> studied how digital technologies can support the conversion towards sustainable production. </div> <div><br /></div> <div>Both Adis and Hasnain used interviews in their research and came across one of the challenges this research method brings. </div> <div><br /></div> <div>“It was very time consuming to listen to all the recorded material afterwards”, says Adis. Hasnain smiled in recognition and agrees but also says that he appreciates the Research Associate Programme. </div> <div><br /></div> <div>“I am grateful for this opportunity. It has been a good experience to get insights about what research is and helps me to make a good decision about whether or not I want to pursue with research”, says Hasnain.</div> <div><br /></div> <div>The forth student is <strong>Shankar Paramasivam</strong>. Unlike the others, he used physical experiments, modelling and analysis in his research. For example he used a single fibre pull-out test to see what force was needed before the bio composite cellulose fibre broke and how the force affected the fibre.</div> <div><br /></div> <div>“I’ve learn a lot about time management and taking up responsibilities. In student projects we usually work in groups and take common responsibility. In this project it was down to me alone and that was a new educative experience”, says Shankar.</div> <div><br /></div> <div>However, the responsibility does not seem to have scared him off. Shankar definitely sees research as a future career path.</div> <div><br /></div> <div>“Yes, I would like to work as a researcher in the future”, says Shankar.</div> <div><br /></div> <div>Adis Imsirovic says that he wants to work in industry first but might come back to research later on. Priska Herzog shares Shankar’s view.</div> <div><br /></div> <div>“I will definitely want to work either as a PhD student or with product development in an innovation driven company”, says Priska.</div> <div><br /></div> <div><strong>The person behind the idea</strong> of the Research Associate Programme is Professor Johan Malmqvist who initially had the ambition to show students some of the benefits of being a researcher. How does he think the program has worked out?</div> <div><br /></div> <div>“I am very pleased with outcome of the programme. It was the first time that is was operated, but it seems that we got the basic design right. Many students applied to the programme. The ones selected worked very hard and, with the engaged guidance from their faculty sponsors, produced very interesting results. In addition, the students expressed that the programme enabled them to develop personally in a way that is not possible in a regular course. The first round of the programme was a clear success”, says Johan Malmqvist.</div> <div><br /></div> <div>So the final question is, will there be a continuation?</div> <div><br /></div> <div>“Yes, the programme will be offered in a similar form the next academic year. Further ahead, we expect the programme to become a regular component of the master’s programmes within the Production Area of Advance, with recognized importance for attracting potential student to Chalmers, for encouraging personal student-faculty interaction, and for stimulating talents students to pursue a research career”, concludes Johan Malmqvist.</div> <div><br /></div> <div><a href="/en/areas-of-advance/production/education/Pages/production-research-associate-programme.aspx" title="Link to basic info about the research associate programme" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Read more about the Production Research Associate Programme​</a></div> <div><br /></div> <h5 class="chalmersElement-H5">For more information, please contact:</h5> <div><a href="/en/staff/Pages/johan-malmqvist.aspx">Professor Johan Malmqvist</a>, Educational Officer of the Production Area of Advance.</div> <div><br /></div> <div><ul><li><span style="background-color:initial">Priska Herzog is studying Product Development and her mentor was Professor Ola Isaksson.</span><br /></li> <li><span style="background-color:initial">Adis Imsirovic is a student in Industrial Design Engineering with Professor MariAnne Karlsson as his mentor. </span><br /></li> <li><span style="background-color:initial">Hasnain Thathia is a student in Production Engineering mentored by Assistant Professor Mélanie Despeisse.</span><br /></li> <li><span style="background-color:initial">Shankar Paramasivam is a student in Applied Mechanics with Associate Professor Martin Fagerström and Professor Gunnar Westman as his mentors.</span><br /></li></ul></div> <div><br /></div> <div><br /></div> <div>Text and photo: Nina Silow</div> ​​Tue, 26 Jun 2018 00:00:00 +0200 2018 jubilee professor wants more philosophy in businesses<p><b>​Professor Claudia Eckert of Open University in the UK is one of Chalmers four jubilee professors in 2018.

This orientation fits well with Claudia Eckert's research. Her research aims at understanding how design processes work and she likes to compare different design areas, from the production of knitted garments in the fashion industry to production of helicopters or trucks. How is it possible to compare such different product areas?<br /><br /></div> <div><span style="background-color:initial">– Looking at the design processes, the similarities are greater than you might think,&quot; says Claudia Eckert. Here you are used to vehicle development, but in the fashion industry you also start with an idea, create a concept and go on producing prototypes and test series before running production. I also believe that the fashion industry has a platform approach where design elements and fabrics are reused in different garments to create a brand recognition and to save money. However, the term platform is not used.</span><br /></div> <div><br /></div> <div>The big difference between the fashion design and product development processes in engineering is the time frame.</div> <div><br /></div> <div>– The process is much faster. Instead of taking several years to develop a new product, a new garment can be made in a week.</div> <div><br /></div> <div>Claudia Eckert looks at processes as a system, or as multiple systems connected with each other. The systems approach is also in line with the research done at Chalmers. She says that the holistic view is necessary to be able to develop products in a sustainable way. Life cycle analysis is a relatively common approach to sustainability aspects of product development, but Claudia does not think that the method is sufficient. </div> <div>“It is a bit too narrow. There may be effects in the environment, at a higher system level, that are omitted. “</div> <div>She gives an example from a German children's program on asparagus cultivation.</div> <div><br /></div> <div>– The Germans love their asparagus in the spring. In one asparagus field they warm up the ground to get an earlier harvest. This sounds devastating from an environmental point of view – if you focus on the heating alone. But in this case the heat came from hot water waste that a nearby factory needed to get rid of and the waste became a resource instead.</div> <div><br /></div> <div>As a help to see the overall picture and act more responsibly, Claudia encourages more philosophy in the corporate world.</div> <div><br /></div> <div>– Yes, I think companies should hire philosophers to get more ethics into the business. It may sound strange, but I think it would help them to make carefully prepared decisions. If there was more philosophical thinking, I think we could avoid scandals like Volkswagen's diesel engines, for example.</div> <div><br /></div> <div>Claudia Eckert has divided her stay at Chalmers into two visits. During the first month she has had a couple of open lectures, participated in the daily research activities and made a number of study visits, both at Chalmers and at collaborating industrial partners. But above all, she has prioritized to talk with PhD students at the department about their research.</div> <div><br /></div> <div>– I am astonished about how open and close cooperation the department has with industrial companies. From this perspective, I think Chalmers is one of the world's leading universities.</div> <div><br /></div> <div>Since the industrial collaboration is so strong, academic positioning is the area where she thinks there is room for growth. By offering the PhD students an academic outside perspective, she hopes to strengthen the quality of their research. She would like to see researchers focusing on issues that create academic debate and more clearly pushes the field of research forward.</div> <div><br /></div> <div><a href="/en/staff/Pages/iola.aspx">Ola Isaksson</a>, research group leader of Systems Engineering Design at Chalmers, was the one who nominated Claudia Eckert as a jubilee professor.</div> <div><br /></div> <div>–​ Claudia Eckert is a well-known researcher who contributes with both deep knowledge in product development and a slightly different perspective which is a positive contribution to the dialogue with researchers and PhD students here.

The cellulose nanocrystals (CNC) that Lilian works with is just the crystalline part of CNF and they are obtained by using acids, says Abhijit Venkatesh and continues:<br /><img src="/en/departments/ims/news/PublishingImages/Ahbijit-Venkatesh_180518_01_170x220.png" class="chalmersPosition-FloatRight" alt="PhD student Abhijit Venkatesh" style="margin:5px 10px" /><br />-    I deal with understanding the processing of cellulose nanofibrils reinforced thermoplastic composites, and how the processing parameters affect the final properties, continues Abhijit Venkatesh. The benefit of using cellulose as reinforcement is that it could help to replace or complement the currently used reinforcements like glass- and carbon fibers. It could also strengthen polymers, which are inherently rather weak, to be used as structural materials.<br /><br />-    My focus is on cellulose nanocrystals. We are trying to customize cellulose to better fit and work with the polymer matrix, but also to understand the challenging mechanisms of cellulose, regarding thermal degradation, moist adsorption and discoloration, says Lilian Forsgren. <br /><br /><strong>Sustainability is a strong driving force</strong>, which go for them both. They give an example of possible new biodegradable product: Consider a milk carton cap made out of plastic. If this plastic were replaced with CNF instead, we could reduce the amount of plastic used to produce the cap. Or even totally degradable if starch or corn could be in the matrix. <br /><img src="/en/departments/ims/news/PublishingImages/Lilian-Forsgren_180518_01_170x220.png" class="chalmersPosition-FloatRight" alt="PhD student Lilian Forsgren" style="margin:5px 10px" /><br />-    I like to be part of the development towards a more sustainable future, no matter how big impact my project will have, every small contribution will make a difference all together, says Lilian and continues:<br />-    I did my bachelor at the Industrial Design Engineering programme at Chalmers but found materials to be very interesting and hence did my master in Materials Engineering. I enjoy challenges and are eager to gain more knowledge. I really enjoy working with cellulose since it is a fantastic material and it’s a more sustainable alternative compared to many materials used today.<br /><br />-    My background differs since I come from Bangalore, India, where I took my Bachelor in the field of Mechanical Engineering. After coming to Sweden 2013, completing my master thesis in Materials Engineering, I found the environment to be calm and productive which pursued me to stay and do my PhD here at Chalmers, says Abhijit. And I like to be part of the move towards a more sustainable society. I think the usage of CNF, which is biodegradable, renewable, abundantly available (in all plant sources) and light weight, in itself is the sustainable perspective. Since the source of cellulose is from Sweden this makes it much more sustainable as Sweden has one of the most sustainable forest industries on the world.<br /><br /><strong>Another interesting fact</strong> – they are both top athletes within in their sports. Lilian Forsgren is running in the <a href="">Swedish national team in Orienteering </a>and  Abhijit Venkatesh play for <a href="">Swedish National Cricket team.</a> Can the competitive spirit be of help in the daily work as a researcher?<br />-    Being determent and setting up a personal goal is a similarity, that might be same the mindset as when I compete in my sport. I set up goals and can be very effective, Lilian says.<br />-    I like to think of research as a team game. I am very good to talking and teambuilding, which is something I learned as a coach in my sport. And to have will power, to have a fixed goal, pushing yourself – that helps, says Abhijit.<br /><br />They agree upon the “never give up&quot;-thing, especially after many failed experiments, you still need to go on.<br />-    Well, there is a competitive downside also, says Lilian. When I had a series of bad turnouts on my experiments, I was really frustrated. But since there is no physical competitor in this case, you must let it go and get back on track.<br /><br /><strong>They are both halfway through </strong>their research and will present their licentiate thesis in September. What are the results so far?<br />-    We have been able to graft side chains onto the molecule of cellulose Nano crystals, performing an increased thermal stability and interesting mechanical properties of the composites produced with these grafted Cellulose Nanocrystals adding them into a polymer matrix, says Lilian. This means we have found a possible way to overcome some of the main challenges such as avoiding degradation at low temperatures and increased strength and thermal stability. <br />-    There are some good results soon to be published, where we managed to make crystal clear, transparent composites that can be used as reinforcement. That is cool, Lilian finishes.<br /><br /><img src="/en/departments/ims/news/PublishingImages/Dihexyl_polymer_foto_Marcus-Folino_300x300.png" class="chalmersPosition-FloatLeft" alt="Transparent composite with cellulose nanocrystals" style="margin:5px" /><img src="/en/departments/ims/news/PublishingImages/Polymerer_cracks_3_foto_Marcus-Folino_300x300.png" class="chalmersPosition-FloatRight" alt="Mixed and dried material, flaky shards." style="margin:5px" /><br /><em><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />Pictures, to the </em><em>left: This is a composite with 10% surface grafted CNC (cellulose nanocrystals) and EAA polymer.

When you put them together they tend to separate and makes the composite more fragile. The main results of my research so far lie in the fact that wet processing techniques is successful in producing excellent composites. It also helps us to achieve high CNF loading contents while not sacrificing mechanical properties. The problem is to upscale the process for industry because it is still too expensive but we will hopefully solve that, says Abhijit.<br /><br /><span>Learn more about the research: <a href="">Surface treatment of cellulose nanocrystals (CNC): effects on dispersion rheology.</a> <br />You can also follow Lilian and Abhijit when they are hosting the <a href="">Chalmers Production</a> instagram account 28-30 May, reporting from <a href="">Nordic Polymer Days 2018, Copenhagen. </a></span>A closely related research within polymer science is presented May 24th at the docent lecture where <a href="/sv/personal/Sidor/roland-kadar.aspx">Roland Kádár </a>talks about <a href="/sv/institutioner/ims/kalendarium/Sidor/Docentföreläsning-Roland-Kádár---IMS.aspx">“Polymer Rheology and Processing”</a>. <br /><br /><br /><strong>Quick facts Lilian Forsgren</strong><br /><strong>Living in: </strong>Gothenburg<br /><strong>Family:</strong> Boyfriend and family with two brothers and two lovely nieces.<br /><strong>Interests: </strong>Love running and nature, especially high mountains.<br /><span><a href="/en/staff/Pages/Lilian-Forsgren.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Read more about Lilian Forsgren</a><br /><a href="/en/staff/Pages/Lilian-Forsgren.aspx"><span style="display:inline-block"></span></a></span><br /><strong>Quick facts Ahbijit Venkatesh</strong><br /><strong>Living in:</strong> <span><strong><span></span></strong>Gothenburg<span style="display:inline-block"></span></span><br /><strong>Family: </strong>Parents, two siblings (who are twins – boy and a girl) and my lovely wife.<br /><strong>Interests:</strong> Love being out in the nature and coaching cricket.<br /><a href="/sv/personal/Sidor/abhven.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Read more about Abhijit Venkatesh</a> <br /><br /><a href="/en/departments/ims/research/em/Pages/default.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Division Engineering Materials </a><br /><br /><em>Text and photo: Carina Schultz<br /><br /><img src="/en/departments/ims/news/PublishingImages/Lilian-Forsgren-Ahbijit-Venkatesh_180518_16_750x340.png" alt="The PhD students in front of a machine" style="margin:5px" /><br />Abhijit Ventaesh and Lilian Forsgren in front of the compression moulding machine, in the Materials Processing Lab at Chalmers, where the samples of composites are moulded.<br /><br /><img src="/en/departments/ims/news/PublishingImages/Lilian-Forsgren-Ahbijit-Venkatesh_180518_13_750x501.png" alt="Samples of composites" style="margin:5px" /><br />Samples of moulded cellulose composites.<br /><br /><br /></em><br />Tue, 22 May 2018 00:00:00 +0200 twins ensure quality and lower costs<p><b>​No one can have escaped the digitalization wave currently under way.

It can have different purposes and is therefore supplied with various real-time data. The digital twin is connected wirelessly to databases and physical devices and is predicted to be common in future production systems.</div> <div>At the same time, the development of simulation models for geometry assurance has been going<span><span></span></span> on for many years.

This means refinement of the digital twin to handle more advanced material properties as multi-material solutions, i.e. solutions in which different materials are used in the same subassembly or the same component. Residual stresses, depending, for example welding details, also affects the geometrical deviation and variation and must therefore also be included in the simulations.</div> <div>-    This means more complex and demanding calculations.

These high temperatures require special materials that can handle the stress in such a warm environment, such as nickel-based superalloys. Among these superalloys, the Ni-base superalloy Haynes 282 has been attracting interest due to its high-temperature properties and weldability. <br />During the pre-study, Ceena Joseph and her colleagues at the division of Engineering Materials, Department of Industrial and Material Science, found a need for better understanding of the heat treatment process and how to optimize it.<br /><br /><span><img src="/en/departments/ims/PublishingImages/Ceena-Joseph_EM_lab_20180410_22_inzoom-struktur_500x500.png" class="chalmersPosition-FloatRight" alt="" style="margin:20px 15px;width:250px;height:250px" /><span style="display:inline-block"></span></span>The fabrication strategy for critical applications such as aero engines was about to be changed from large cast parts into welded structures of forged multi-material goods. Something that required adapting the right heat treatment in order to get the right mechanical performance. <br /><br />The challenge is to tailor the heat treatment to suit the multi-material structures and still be able to meet the desired property requirements. <br /><br />-    This requires a profound understanding of the process-structure-property relationships for these complex alloys, says Ceena Joseph.<br /><br />Her research focusses on different heat treatments, how to optimize it and the sensitivity in the treatments. For instance, what happens in the microstructure during temperature changes? Are the mechanical properties stable? <br /><br /><span><img src="/en/departments/ims/PublishingImages/Ceena-Joseph_EM_lab_20180410_72_340x305.png" class="chalmersPosition-FloatRight" alt="" style="margin:5px 15px;width:250px;height:225px" /><span style="display:inline-block"></span></span>-    We have been able to understand the sensitivity of this alloy for different heat treatment conditions, which primarily occurs due to changes in its microstructural constituents. These microstructural changes affect the mechanical properties of the alloy, which can hence be tailored by heat treatment.<br />The research results show that, within the process variation mechanical properties are stable after the heat treatment. The method works well and provides good strength.<br /><br />-    Simply put, we can rely on the production process and fly safe, explains Christer Persson, professor and head of Division for Engineering Materials.<br /><br />Ceena Joseph recently defended her doctoral thesis “Microstructure Evolution and Mechanical Properties of Haynes 282”.

This new knowledge is important for oil, gas, food and nuclear industries – and for your kitchen pots.</b></p>​<img src="/SiteCollectionImages/Institutioner/IMS/Material%20och%20tillverkning/Giulio%20Maistro_200x250.png" class="chalmersPosition-FloatRight" alt="Giulio Maistro" style="margin:5px;width:170px;height:213px" /><span style="background-color:initial">In a recently published doctoral thesis, <a href="/sv/personal/Sidor/maistro.aspx" target="_blank">Giulio Maistro</a> presents studies of methodologies to make austenitic stainless steel harder, without losing the &quot;stainless&quot; properties. The results show that it is important to consciously balance the different metals used in the steel, as well as the additives nitrogen and carbon.</span><div><br /></div> <div><strong>Austenitic stainless steel </strong>is a specific type of stainless steel alloy that is used for kitchen pots and many industrial applications. This type of material is very good to use with strong acids or salty water because it is resistant to corrosion. </div> <div><br /></div> <div><span style="background-color:initial">Unfortunately, today’s stainless steel has the drawback of being very easy to scratch and damage. It is too soft. This is not crucial for our kitchen ware, but is a big problem for jewellery or for industrial applications. In industrial sectors like the oil, gas, food and nuclear industries, the surface has to be smooth like a mirror. </span><br /></div> <div><br /></div> <div><strong>When making stainless steel</strong>, it is the combination of the material in itself and the surface treatment that defines how good the result is. The result of a surface treatment can be radically different depending on the formula the material is composed of. Giulio Maistro says that this can be both a good and a bad thing. </div> <div><span style="color:black;font-family:calibri,sans-serif;font-size:11pt;background-color:initial"><br /></span></div> <div><span style="color:black;font-family:calibri,sans-serif;font-size:11pt;background-color:initial">– </span>Nowadays, we have reached a stagnation in the application of surface treatments like plasma, gas nitriding or carburizing. More or less everyone in the field knows &quot;when it is worth to use them and when it is not&quot;. </div> <div><br /></div> <div>According to Giulio Maistro, companies keep their processes secret which makes process development hard and almost completely abandoned in academia. Giulio Maistro’s research is welcomed. Not much research has been done earlier on the optimization of the materials to fit the treatment. Instead of trying to change and over-optimize the treatment parameters, it could be easier and more effective to tailor-make a new material that better matches the treatment.</div> <div><br /></div> <div><strong>This tailor-making involves</strong> <strong>Nickel and Molybdenum</strong>, two metals that typically are added into the steel to improve resistance against corrosion. </div> <div><span style="color:black;font-family:calibri,sans-serif;font-size:11pt;background-color:initial"><br /></span></div> <div><span style="color:black;font-family:calibri,sans-serif;font-size:11pt;background-color:initial">– </span>In my research I show that by adding Nickel it is possible to decrease the unwanted formation of carbides, which are bad for corrosion. However, when too much Nickel is used, the material cannot be hardened very much. This is because carbon and nitrogen do not like Nickel and vice versa. If you use the metal Molybdenum, the opposite effect is shown. </div> <div><br /></div> <div>To harden the steel, it is common to introduce nitrogen or carbon in it. The more nitrogen or carbon you have, the harder the steel gets. This relates to Nickel and Molybdenum. Depending on how much of those metals you have in the steel, you can change how much nitrogen or carbon you can introduce in it. </div> <div><br /></div> <div>However, if you introduce too much nitrogen or carbon, chemical compounds called nitrides and carbides are formed. When they form, the stainless property of the steel gets lost. In general, Molybdenum increases the amount of nitrogen or carbon you can insert. Nickel limits the amount but also limits the formation of nitrides or carbides. </div> <div><span style="color:black;font-family:calibri,sans-serif;font-size:11pt;background-color:initial"><br /></span></div> <div><span style="color:black;font-family:calibri,sans-serif;font-size:11pt;background-color:initial">– </span>This new knowledge shows that companies that manufacture products made of stainless steel need to find a balance between Nickel and Molybdenum to get the maximum hardness while maintaining the stainless properties, upon introducing nitrogen or carbon, says Giulio Maistro.</div> <div><br /></div> <div><strong>FACTS:</strong></div> <div>Gas nitriding or carburizing are methods to introduce nitrogen or carbon to the steel.</div> <div><br /></div> <div><a href="/sv/personal/Sidor/maistro.aspx" target="_blank">Giulio Maistro​</a> performed his doctoral studies at the <a href="/en/departments/ims/research/mm/Pages/default.aspx">division of Materials and Manufacture</a> which belongs to the <span style="background-color:initial"><a href="/en/departments/ims/Pages/default.aspx">department of Industrial and Materials Science</a> at <a href="/en/Pages/default.aspx">Chalmers University of Technology</a>.

Four students from four different master programs have been appointed as the pioneering research associates. Product development in sports, Scandinavia-Balkan industrial design comparison, sustainability in connection to digital technologies and bio-composites are their topics of interest.</b></p>​<span style="background-color:initial">The number of young educated people is decreasing around the world and in the future it will be a fierce competition regarding recruiting young engineers. This is recognized in industry but also by universities. Chalmers wants to secure a new generation of researchers but not everyone knows what it is like to work as a researcher. The Production Area of Advance now launches a new Research Associate Programme. <a href="https://en/Staff/Pages/johan-malmqvist.aspx">Professor Johan Malmqvist who is the Education Officer within the Production Area of Advance​</a> explains the purpose of the programme.</span><div><br /></div> <div>– I really like my job as a researcher and this is an opportunity to show students some of the benefits of being a researcher. With this programme, we want to enable talented students from our master programmes to obtain some experience from research activities such as developing research plans, carrying out simulations or experiments, analyzing data and presenting or publishing your results.</div> <div><br /></div> <div>The programme is inspired by the “Undergraduate Research Opportunity Programs” often found at US universities. However, the structure is unique for the Production Area of Advance Research Associate Programme. It is meant to have a bottom-up approach. If interested in applying for a position in the programme, students are urged to take the initiative to make contact with a faculty member with a project idea. The idea is then put into an application and, if the application is granted, the research associate will receive a senior researcher as mentor during the project. Projects are to be reported both mid-term and in the end of the spring term. </div> <div><br /></div> <div><strong>The pioneers of this seed-bed programme are four students from four different master programmes.</strong></div> <div><br /></div> <div><strong>Priska Herzog</strong> is studying <a href="/en/education/programmes/masters-info/Pages/Product-Development.aspx" target="_blank">Product Development</a> and her mentor is <a href="/en/staff/Pages/iola.aspx">Professor Ola Isaksson</a>. Priska is very active in her spare time and like adventurous sports like snowboarding, surfing, kayaking and mountain biking. She also takes her interest a step further and has e.g. developed and built an own snowboard. Her research associate project is therefore linked to her burning interest in sports. The title is “Involve R&amp;D in sports in product development”. But why is sports interesting for product development research? Priska explains her view.</div> <div><br /></div> <div>– Sport athletes differs from other consumers in that they are very experimental in finding advantages that can make them win in a competition. Sports technology therefore often includes short product development cycles, rapid prototyping, and a collaborative customer that need better products to win and brings immediate feedback and a personal connection. This area is also somewhat less cost sensitivity than other consumer areas. We tend to put money on our hobbies.</div> <div><br /></div> <div>With this project Priska wants to raise awareness about sports technology in product development to improve the offering of sports projects for students and to improve the contact areas between Chalmers and sports.</div> <div><br /></div> <div><strong>Adis Imsirovic </strong>is a student in <a href="/en/education/programmes/masters-info/Pages/Industrial-Design-Engineering.aspx" target="_blank">Industrial Design Engineering</a> with <a href="/en/Staff/Pages/helena-stromberg.aspx">Senior Lecturer Helena Strömberg</a> as his mentor. </div> <div><br /></div> <div>– I am born and raised in Sweden but my family is from Bosnia and we have spent all summer holidays there. During my upbringing I have developed a curiosity about if the design thinking in the two cultures differs. </div> <div><br /></div> <div>The research associate programme gives Adis the opportunity to dive into this question. His project is called “Do designers from Scandinavia interpret design differently from designers in Balkan?”. Adis wants to perform a study where he meets universities and teachers as well as product development departments in companies in both Sweden and Balkan countries. Are there any differences? If yes, how would it be possible to cooperate spite the differences and what difficulties would occur? </div> <div><br /></div> <div><strong>Hasnain Thathia</strong> is a student in <a href="/en/education/programmes/masters-info/Pages/Production-Engineering.aspx" target="_blank">Production Engineering</a> mentored by <a href="/en/Staff/Pages/melanie-despeisse.aspx">Assistant Professor Mélanie Despeisse</a>.

The title of Hasnain’s project is “The influence of digital technologies towards sustainable production”.</div> <div><br /></div> <div>– My aim is to review digital technologies in the manufacturing industry and assess their potential to improve performance with a specific focus on environmental sustainability. These technologies include software for modelling and simulation, virtual/digital factory, cloud computing and sensors which play a huge role in Industry 4.0. I would like to evaluate the performance of these digital technologies implemented in industries and compare them with the traditional technologies from a sustainable perspective (energy, waste, material usage, data accuracy).</div> <div><br /></div> <div><strong>Shankar Paramasivam</strong> is a student in <a href="/en/education/programmes/masters-info/Pages/Applied-Mechanics.aspx" target="_blank">Applied Mechanics</a> with <a href="/en/staff/Pages/martin-fagerstrom.aspx">Associate Professor Martin Fagerström</a> and <a href="/en/staff/Pages/gunnar-westman.aspx">Professor Gunnar Westman​</a> as his mentors. In his project, Shankar faces a bit of a challenge since his background is from mechanical engineering and the projects includes quite a lot of chemistry. This project also differs from the others since it is initiated by the mentor and not the student. The title is “Supporting the upscaling of sustainable biocomposites from cellulose fibres for use in structural components”.</div> <div> </div> <div>– The aim of the project is to support research to find a more sustainable alternative to the commonly used composites carbon fiber composites and glass fiber composites that are non-biodegradable and takes a lot of energy to produce.</div> <div><br /></div> <div>Even if the subject is new to Shankar, he finds the project very interesting.</div> <div><br /></div> <div>– It combines the mechanical engineering knowledge that I already have with a new area.
