ABSTRACT

New high-performance materials can play a vital role in improving many aspects of the modern economy. However, developing a new material with an optimum set of properties involves trillions of possibilities. Which elements to choose, what should be the crystal structure, which is the best processing route, what are the optimum processing parameters etc.? The conventional approach is to start with one or two compositions, synthesize the material by one route, and perform characterization and property evaluation. 

This approach typically takes 20-30 years to develop a new material for real applications. On the other hand, the accelerated discovery approach starts with a large number of compositions and relies on high throughput synthesis, characterization, property evaluation, predictive machine learning modelling to rapidly screen a huge number of compositions1, 2.  

This approach can cut the development time to ~3-4 years and identify completely new attractive compositions. We have deployed several advanced high throughput techniques such as additive manufacturing, spark plasma sintering, chemical flow synthesis, magnetron co-sputtering and machine learning to rapidly discover new high-performance materials1, 3. Compositions with an optimum magnetic-mechanical-electrical property set, required for next generation energy conversion machines, have been identified by our approach. Our results demonstrate the attractiveness of high throughput techniques for the quick development of high-performance materials.
