Many High Entropy Alloys (HEAs) have been reported to form single-phase solid solutions in the center of the phase diagram. The high number of components in such alloys, typically five or more, opens a vast high-dimensional phase space to be mapped and characterized. Doing so with common bulk metallurgical methods only is challenging because this approach is costly and time consuming.
We apply high-throughput combinatorial methods (co-sputtering and characterization) to investigate HEAs. This technique allows us to quickly and efficiently map alloy systems (up to 600 alloys per time) with respect to their composition, phase structure and properties. Data generated can verify whether criteria reported for the formation of single-phase solid solutions, e.g. atomic size criteria, hold true and allows us to search for new trends and alloys. Our high-throughput combinatorial approach offers a valuable tool to develop new HEAs.
