High strength and low density are the basic requirements for the materials used in the aeronautical field, the engine materials need high temperatures resistance more severely. High entropy alloys (HEAs) containing refractory metal elements with high melting point show excellent material properties at high temperature. At present, more than 120 kinds of refractory high entropy alloys (RHEAs) have been synthesized, and their physical and mechanical properties, such as density, tensile properties, compression properties, elastic modulus and antioxidant properties have been tested experimentally. In this paper, the performance parameters of refractory high entropy alloys and traditional typical aviation materials are summarized, and the density and yield strength limits of refractory high entropy alloys at high temperature are compared, most refractory high entropy alloys show high mechanical strength and microstructure stability.
