摘　　要：合金的性能首先取决于材料的组元,这是材料的基因,准确设计合金元素对材料力学性能的相应变化是建立成分-结构-性能关联性的关键环节。本文从高熵合金概念出发,综述了高熵合金的有关研究文献,详细介绍了多种常用高熵合金元素的功能作用,总结了主元元素对高熵合金组织和性能的影响,展望了高熵合金未来的发展趋势,以期对高熵合金开发和应用提供有益参考。The performance of alloys depends on the constituents of the material,which is the gene of the material.Accurately designing the corresponding changes of alloy elements on the mechanical properties of materials is the key link to establish the relationship between composition-structure-performance.Starting from the concept of high entropy alloys,this paper summarizes the relevant research literature of high entropy alloys,introduces in detail the functional role of a variety of commonly used high entropy alloy elements,and summarizes the influence of primary elements on the microstructure and performance of high entropy alloys.The future development trend of high entropy alloys is prospected,in order to provide useful reference for the development and application of high entropy alloys.
