摘要：
There is no identification of solute and solvent in high entropy alloys, compared to traditional alloy materials. The lattice distortion and size mismatch caused by the special composition of high entropy alloys make it possess significant solid solution strengthening effect, and hence lead to excellent mechanical strength. However, classical strengthening theories based on diluted solute assumption cannot be used to describe the strengthening effect of high entropy alloys, so it is hard to accurately predict the strength of high entropy alloys, which hinders the rational design and application research of such alloys. In recent years, some researchers explore the solid solution strengthening origin and try to develop reliable strengthening models to realize the high-throughput prediction of strength/hardness, and ultimately guide the rapid composition design for performance requirement, to promote the scientific research and engineering application of high entropy alloys. In this review, we summarized the research progress on solid solution strengthening of high entropy alloys, introduced three typical strengthening models at present, compared and analyzed the model construction, prediction effect, remaining problems and the specific application in the design of high entropy alloys. Finally, we prospected the exploration of solid solution strengthening mechanism of high entropy alloys, the development and application of strengthening model. © 2021, Materials Review Magazine.
