Abstract:

High-entropy alloys have attracted extensive attention due to its new design concept and excellent performance. As a kind of high-entropy alloy, refractory high-entropy alloys are mainly composed of BCC crystal structure, which has the characteristics of high strength and high hardness as well as the high temperature softening resistance. In this paper, the preparation method, Phase structure, microstructure, mechanical properties and application fields of refractory high entropy alloy were described, and its directions of future research are also discussed.
