The division of Materials and Manufacture covers the entire value chain from materials design, processing and characterisation to machining of primarily metals. We employ a range of technologies – powder metallurgy, electroplating, additive manufacturing and material removal – and a range of advanced characterisation techniques. Our work is interdisciplinary by nature and is addressing topics that have a direct impact on sustainability. The division is collaborating closely with other universities and research institutes and is implementing industry-academia partnerships through collaborative projects and strategic initiatives such as the Chalmers Centre for Metal Cutting Research (MCR). The work is conducted in the following three research groups:
The Powder and Surface Technology Research Group
combines core competencies in powder metallurgy science and surface science to develop materials and processes with respect to materials design and surface or interface control. The group focuses strongly on metal-based additive manufacturing as well as metal powder sintering, but extends also its research to different areas (surface coatings, machining, oxidation, corrosion) where understanding and characterisation of surfaces is important. Surface chemical characterization (XPS. Auger), thermal analysis (DSC; TGA, dilatometry) and application of thermodynamic and kinetics modelling are core tools in the research besides latest equipment for additive manufacturing with powder-bed laser melting.
The Surface and Microstructure Engineering Research Group
uses electron microscopy (SEM, TEM) in combination with all necessary complementary techniques to examine the structure-property relationship of engineering materials (metals and ceramics). The investigated materials range from nanomaterials, different types of coatings, to advanced steels and superalloys. We also produce and explore high-entropy alloys (HEAs). Moreover, materials characterisation is used for studying production and machining influences with the aim to optimize manufacturing processes and improve the performance of components.
The Manufacturing Technology Research Group
advances manufacturing primarily through fundamental research, concentrating on modelling, simulation and optimisation of machining operations. The core competencies of our research include a distinctive modeling framework combining numerical models of machining with simulation of materials in order to predict the outcomes of metal-cutting phenomena such as tool wear. We also specialise in grinding and abrasive technologies, working directly with industry to innovate processes and apply new methods.
