Research in the field of high-entropy alloys has been surging since the 2010s. As widely acknowledged, research interests in this field are largely sparked by the enormous possibilities in compositions, microstructures, and properties. In the first decade of extensive investigations, while many avenues of research in this vibrant field are being continuously opened, a considerable portion of endeavors is directed toward two very fundamentally important aspects. One is the exploration of the huge compositional space and microstructures with the aid of thermodynamics and kinetics, while the other is the characterization and comprehension of their mechanical behavior from fundamental and practical perspectives. Each of these two aspects contains numerous, scattered, sometimes confusing or conflicting data and findings in the literature. Thanks to several excellent comprehensive reviews [1–3], the accomplishments and challenges in the first aspect are neatly presented to researchers in the field. Nonetheless, the second aspect, i.e., the mechanical behavior of high-entropy alloys, is still largely afloat in abundant literature in a spite of some recent reviews on certain specialized topics [4–6]. In consideration of this insufficiency, the present review intends to offer a comprehensive, critical review of the mechanical behavior of high-entropy alloys and some closely related topics.

自2010年代以来，高熵合金领域的研究一直在蓬勃发展。众所周知，该领域的研究兴趣很大程度上是由组成，微观结构和性质的巨大可能性激发的。在广泛研究的第一个十年中，尽管这个充满生机的领域的许多研究途径正在不断开放，但相当一部分工作是针对两个非常重要的方面。一种是借助热力学和动力学探索巨大的成分空间和微观结构，另一种是从基本和实际的角度对它们的力学行为进行表征和理解。这两个方面的每一个都包含大量，分散的，有时令人困惑或矛盾的数据和文献中的发现。多亏了几篇优秀的综合评论[1-3]，第一方面的成就和挑战才能清晰地呈现给该领域的研究人员。尽管如此，第二个方面即，高熵合金的力学性能，仍然在大量的文献主要是漂浮在尽管对某些专门课题[4-6]最近的一些评论。考虑到这种不足，本综述旨在对高熵合金的力学行为和一些紧密相关的主题进行全面，严格的综述。
