| Abstract Scope |
The concept of multi-principal element alloys (MPEAs) opens new compositional spaces leading to millions of unexplored alloy possibilities. How do these alloy configurational differences influence properties and behavior, and what variables control such alloy properties? This requires establishment of new theories to explain and predict solid solution strengthening, surface passivity, or functional properties in MPEAs. Recent developments in efficient, high-throughput computational tools and high throughput experiments for structural materials and screening alloys for passivity studies provide the foundation for new materials discoveries. These offer high throughput calculations of ground state crystal structures and the distorted atomic positions in MPEAs, for exploring diffusion and dislocation motion, and passivity, and how configurations lead to different functional and structural properties and how are those properties may be related to chemical composition and processing variables. This promises to activate data-driven studies in MPEAs. |
