With the continuous improvement of the requirements of advanced engineering technology on the performance of shape memory alloys, traditional shape memory alloys are increasingly difficult to meet the requirements. High entropy shape memory alloys have emerged as the times require, which has attracted great attention of researchers.Compared with traditional shape memory alloys, high entropy shape memory alloys have significantly improved recoverable strain, yield strength,high temperature phase stability and hyperelasticity, and have broad application prospects. In this paper, the research status, martensitic transformation and shape memory effect of high entropy shape memory alloys are briefly reviewed,and the existing shortcomings and future development of high entropy shape memory alloys are prospected.
