Abstract Compared with traditional alloys, high entropy alloys possess excellent mechanical properties, which
have become a hot spot in recent years. Refractory high entropy alloy is mainly composed of refractory metal elements,
which has high strength and high temperature resistance, so it has great potential for application in extreme
environment. However, there are still some problems such as strength-plastic mismatch and poor processability
in refractory high entropy alloys. It is the focus of research to regulate the microstructure of refractory
high entropy alloys then improve strength and plasticity. In this paper, the preparation methods of refractory high
entropy alloys were compared, the effects of regulating metal and nonmetal elements on microstructure and mechanical
properties of refractory high entropy alloys were discussed. At the same time, the functions of thermal
machining on mechanical properties of refractory high entropy alloys were investigated.
