摘要(Abstract)：

目前，高熵合金因其高强度、高硬度以及优秀的热稳定性等远超传统意义上合金的性能，引起了大批科研工作者的关注。其中，面心立方结构(FCC)的CoCrFeMnNi高熵合金表现出良好的塑性及77 K温度下优异的断裂韧性，但是其室温强度较低，极大地限制了其在工业中作为结构材料的应用前景。本文综述了间隙原子(C、N、B)以及颗粒增强相对CoCrFeMnNi高熵合金组织和性能的影响，重点阐述了掺杂间隙原子的高熵合金显微组织、变形行为和力学性能的研究进展，并对颗粒增强高熵合金复合材料的研究现状进行了归纳，最后对CoCrFeMnNi高熵合金未来的强韧化研究和发展方向提供了一些思路。
