Meeting the design requirements of the next generation of high performance transportation systems, power generators, and energy storage devices requires the discovery and development of new structural alloys with enhanced properties. Multi-principal element alloys (MPEAs), consisting of several constituent elements but no dominant solvent species, represent a vast yet under-explored design space due to the time-consuming nature of traditional alloy design methods. The objective of this collaborative project is to investigate the role of chemical composition on the phase-stability and mechanical properties of MPEAs using a high-throughput approach.
This project is funded by the National Science Foundation, Grant No. DMR-1809571. The Principal Investigators are Katharine M. Flores and Rohan Mishra.
