At present, the research of high entropy alloys is mostly focused on the fields of bulk, powder, coating, film, etc., and the research in other fields is less and lacks a unified classification. In this paper, based on the current research progress of high entropy alloys, all kinds of high entrop ...

Refractory high entropy alloys (RHEAs) form multi principal alloys with equal or near equal atomic ratios by adding a variety of refractory elements. They have simple phase structures and excellent high temperature properties, and have extremely broad application prospects in the field of superal ...
