Abstract Eutectic high-entropy alloy is a novel alloy system which has excellent mechanical properties. Its typical lamellar eutectic structure is generally composed of soft phase and hard phase, and eutectic high-entropy alloys can have high strength as well as good plasticity. This main characteristic of mechanical properties makes eutectic high-entropy alloys have a wide application area in industrial field. This paper introduces the concepts and features of eutectic high-entropy alloys. The recent developments of mechanical properties and deformation behavior of eutectic high-entropy alloys are summarized. The problems on the formation mechanism of phase and microstructure evolution during deformation are put forward,and the future development trends are prospected. Hope that this paper could provide ideas for optimizing the mechanical properties of eutectic high-entropy alloys.
