摘 要: 高熵合金的多主元特征，使其在变形过程中表现出多种变形机制的协同作用，因而表现出优异的性能。与传统合金相比较，对高熵合金中多种变形机制调控的可能性更大。研究发现，微结构及其演变将直接影响合金中的变形机制，通过“微结构-变形机制-性能”这一设计思路，在高熵合金中引入多变形机制并调控其激活顺序成为今后研究高熵合金的重点。本文对FeCoNiCrMn系高熵合金变形机制的研究现状进行了综述，总结了高熵合金中常见的几种变形机制，并对高熵合金中变形机制的研究进行了展望。

Abstract:The multi-principal component characteristics of high entropy alloy make it show the synergistic effect of variety of deformation mechanisms in the deformation process, and then exhibit excellent properties. Compared with traditional alloys, it is more possible to regulate various deformation mechanisms in high entropy alloys. It is found that the microstructure and its evolution will directly affect the deformation mechanism in the alloy. Through the design idea of "microstructure-deformation mechanisms-properties", introducing multi-deformation mechanism into high entropy alloy and regulating its activation sequence has become the focus of high entropy alloy research in the future. In this paper, FeCoNiCrMn alloy system is taken as an illustrative example for the current discussion and summary research status of several deformation mechanisms in alloys. Finally, the future research on deformation mechanism in high-entropy alloys is prospected.
