Abstract：
High entropy alloy is a new type of multi-main element alloy,which shows excellent properties such as high strength,high hardness,wear resistance,thermal stability and corrosion resistance due to its unique microstructure.In recent years,it had been found that the high-entropy alloy of transition family elements with excellent properties is mostly FCC structure,and the phase structure can be predicted by calculating the parameters such as atomic radius difference,mixed enthalpy,configuration entropy and valence electron concentration of high-entropy alloys.However,the relationship between the phase structure,evolution and properties of such alloys is not clear.The structure,phase structure evolution and properties of FCC high-entropy alloy are reviewed,and its future development is prospected.
