Abstract

Minor- and macro-alloying has long been used to achieve desirable properties to metallic materials. This traditional alloy design strategy involves adding a small number of secondary elements to a primary element for optimized properties. In the early twenty-first century, a new multiple principal elements alloying strategy called high-entropy alloys (HEAs) emerged. This alloy design strategy has overwhelming advantages over traditional alloys in seeking high performance, since it provides an infinite compositional design space and lots of HEAs with outstanding properties have been developed. The objective of this chapter is (1) to summarize the basic and salient features of HEAs, (2) to review the mechanical properties of HEAs with the face center cubic structure at low temperatures and hydrogen-containing environments, and (3) to assess the recent advancement in precipitated-strengthened high-entropy alloys.
