| Abstract Scope |
For ICME accelerated design and development of multiple-principal-elements alloys (MPEAs), including refractory-based as promising materials for next-generation energy technologies, we present a theory-guided approach in down-selecting high-temperature MPEAs having high-strength and ductility. We showcase simple quantitative metrics to predict and to assess rapidly properties for arbitrary solid-solution alloys, in particular strength and ductility. For example, the intrinsic strength of any solid-phase metal (single- and poly-crystal and amorphous) is obtained directly from a physical metric available from any density-functional theory (DFT) code. For design, these predictions inform bulk combinatorial synthesis and characterization to verify down-selection of superior mechanical properties, or other properties including catalysis. Examples for numerous systems will be discussed. |
