摘　　要：高熵合金作为一类新型的合金,具有许多优于传统合金的性能,在诸多领域有广阔的应用前景。高熵合金现阶段的研究主要集中在其力学性能方面,它的高强度、高硬度、高耐磨性和耐腐蚀性等优点展现出了其作为在严酷条件下服役的结构材料的潜力,但目前对高熵合金的研究仍处于探索性阶段,所以研究高熵合金的力学性能具有重要的现实意义。主要综述了组分、制备工艺、热处理工艺、冷轧等对高熵合金的组织与力学性能的影响,并展望了高熵合金的应用前景。High entropy alloys(HEAs)is a new kind of alloy with many properties superior to traditional alloys,and it has broad application prospects in many fields.At present,the research of high entropy alloys mainly focused on the mechanical properties,its high strength,high hardness,high wear resistance and corrosion resistance and other advantages manifest its potential as a structural material to serve under harsh conditions,but the current research of high entropy alloy is still in the exploratory stage.Researches on the mechanical properties of HEAs will be necessary and significant.In this paper,the effects of composition,preparation,heat treatment,and cold rolling on the microstructure and mechanical properties of HEAs are reviewed,and the application prospect of HEAs is also discussed.
