The current research status of refractory high-entropy alloys(RHEAs) is reviewed,the composition design of RHEAs is described,and the effects of metal elements and non-metal elements on the structure and properties of RHEAs are summarized. In addition,the microstructure and mechanical properties of RHEAs under different preparation methods are described,and the strengthening mechanism of RHEAs matrix composites is discussed. The future development of RHEAs is prospected,and the following suggestions are put forward for its future research direction: enhancing of RHEAs by multiphase synergistic effects through the interface design between different phases;designing and optimizing the composition of RHEAs to develop RHEAs that are easy to process at room temperature;quickly screening the composition and microstructure of RHEAs by combining with high-throughput calculation methods;regulating and controlling the microstructure and structure of RHEAs by additive manufacturing technology;carrying out the configuration design of RHEAs matrix composites to balance the strength and plasticity of RHEAs matrix composites.
