Tailoring heterogeneities in high-entropy alloys to promote strength-ductility synergy. [PDF]

Nat Commun, 2019
Conventional alloys are usually based on a single host metal. Recent high-entropy alloys (HEAs), in contrast, employ multiple principal elements. The strength of HEAs is considerably higher than traditional solid solutions, as the many constituents lead ...
