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. A clear challenge is harnessing MPEA composition and microstructure to realize the potential oxidation and corrosion resistance by producing a self-healing passivation layer. With millions of permutations of MPEAs in existence, however, it’s virtually impossible to nail down the “right” combination without innovation. This talk presents a combinatorial, high throughput approach to alloy discovery that enables assessment of thousands of MPEAs. Results for alloy systems that result from a combined theory and experiment effort reveal the benefit of such an approach to explore currently untapped compositional space toward alloy phase evolution and predict and control passivation/complex oxide evolution, |
