Abstract: High entropy alloys have attracted much attention because of their unique structure and properties. However, it is difficult for high entropy alloys with single-phase solid solution structure to combine the comprehensive performance of high strength and good plasticity. Dual-phase high entropy alloys are expected to realize the comprehensive mechanical properties of high strength and good plasticity due to the mechanical advantages of different phase structures and the interactions between the phases during deformation, which has become a major hotspot in the research field of high entropy alloys. It outlined the compositional design guidelines for dual-phase high entropy alloys, listed the structure and performance characteristics of four common dual-phase high entropy alloys, such as eutectic, amorphous, precipitation-strengthened and metastable types, the effects of elemental variations and heat-treatment processes on the microstructure and performance of dual-phase high entropy alloys were summarized, and the development trend of dual-phase high entropy alloys was prospected.
