Abstract Scope |
Multi-Principal Element Alloys (MPEAs) are the subject of emerging interest due to their compositional profile, which holds the promise of superior mechanical properties, high thermal stability, and high strength at high temperature. It is critical to understand the atomic to mesoscale tuning parameters for MPEAs to harness critical properties, such as high yield strength, low mass density, and corrosion/oxidation resistance for materials in coatings, propulsion, energy absorption and hypersonic vehicles. With millions of permutations of MPEAs in existence, however, it’s virtually impossible to nail down the “right” combination without both rapid assessment and innovation. Here we present a path forward for high throughput, physics informed alloy design, informatics, synthesis, and characterization. Our high throughput approach enables tracking, curation, and dissemination of thousands of possible MPEAs. We show that untapped compositional space, combined with precision processing, is a promising path toward realizing MPEA potential. |
