Abstract:

High-entropy alloys(HEAs) were a new class of alloys that have attracted physical and chemical properties. The light-weight high-entropy alloys with light elements have high specific strength, specific hardness and corrosion resistance. Light-weight HEAs have attracted worldwide attention for their outstanding potential value in the field of engineering application. Therefore, in this paper, the research status of light-weight high-entropy alloys was elaborated, including that the design rules and methods of light-weight HEAs were assessed, the microscopic phase structure of lightweight HEAs were analyzed, and different properties of HEAs were summarized. Accordingly, current problems of light-weight HEAs are also discussed, and the development trend of light-weight HEAs is proposed.
