Equiatomic CoCrFeMnNi alloy, one of the most widely studied highentropy alloy, has many excellent properties beyond traditional alloys, including remarkable plasticity, stable phase structure, outstanding cryogenic mechanical properties, etc., which endow it with great development potential and extensive application prospects. The microstructure characteristics of the CoCrFeMnNi alloy fabricated by various fabrication methods were summarized, and the advantages and disadvantages of these fabrication methods were briefly discussed. The mechanical properties and deformation behaviors of the alloy were mainly analyzed, including the effects of different strengthening methods on the mechanical properties of the alloy and the mechanical properties and deformation mechanisms of the alloy at cryogenic temperature and high temperature. The research progress of the phase stability of the alloy was also introduced. Finally, the major problems restricting the development of the alloy were discussed, and the future development direction of the alloy was prospected.
