With the continuous development of human society and the increasing demand for materials, people have put forward some brand new demands for the application of materials in different fields, and the concept of multiple alloy design has been proposed to provide an unlimited composition space for alloy design. High entropy alloys (HEAs) are composed of multiple primary elements. This system not only increases the mixed entropy of the alloy but also enables a high concentration of solid solu-tion to be obtained, avoiding the formation of more brittle intermetallic compounds, and giving it a comprehensive performance that is difficult to have with other conventional alloys. However, mate-rials serving in extreme environments need to have high toughness and high strength at the same time, and the existing alloys cannot meet these nearly demanding requirements, researchers in re-cent years through a variety of toughening means to make the performance of high- entropy alloy be greatly improved. This paper summarizes, analyzes, and reviews the latest research progress at home and abroad in terms of the composition, phase structure, and means of toughening high-entropy alloys. %K 高熵合金,强度,塑性,强韧化
