Application of high-pressure technology in exploring mechanical properties of high-entropy alloys

In recent years, high-entropy alloys (HEAs) have developed a lot as the new style of materials, which have become a research focus in the materials fields. It breaks the normal procedure of traditional alloy design (based on one/two elements as the main component, and adds some other elements to improve the microstructure and required related performance of the alloy), and consists of five or more equal or nearly equal elements, with multiple principal elements. Therefore, HEAs have many excellent mechanical properties compared with traditional alloys, which have aroused great research interest of researchers. The rapid development of high-pressure technology makes it a powerful tool to modulate the structures of HEAs, and brings new chance for the study and optimization of mechanical properties of HEAs. In this paper, the application of high-pressure technology in exploring and improving the mechanical properties of HEAs is reviewed, which could deepen the understanding of high-pressure technology and provide a new avenue for further exploration of HEAs’ mechanical properties.
