【Abstract】 High entropy shape memory alloy is a novel type of high temperature shape memory alloy, which is developed on the basis of NiTi alloy with equal atomic ratio and the concept of high entropy alloy. In recent years, the(TiZrHf)50(NiCoCu)50 and(TiZrHf)50(NiCuPd)50 series high entropy shape memory alloys with excellent comprehensive properties were developed, which has attracted extensive attention and research interest. In this paper, the research progress of high entropy shape memory alloy was reviewed from the aspects of phase composition, microstructure, martensitic phase transformation behavior, shape memory effect and superelasticity.Simultaneously, the future investigate keynote of high entropy shape memory alloy was also prospected.更多还原
