Abstract High-entropy alloys, which broke through the design concept of traditional alloys with one or two elements as the main element,and deve-loped alloy design system to the field of multiple elements.The types and contents of main elements of high-entropy alloys are variable, showing different characteristics in macroscopic properties and microstructures, but the development of alloys is still limited to the experimental exploration stage, and it is difficult to give accurate guidance to the development of alloys through existing theories. For the problems existing in this field,researchers have found that the alloying elements affect the overall performance through lattice distortion, elements with larger atomic radii such as Al, Ti, V, and Mo, and elements with smaller atomic radii such as Si and B can change the alloy's properties by intensifying lattice distortion.This paper focuses on the classification and summary of common elements in high-entropy alloys by studying the existing theories, and analyzes the influence of alloying elements on the characteristics of high-entropy alloys.Finally, it summarizes the issues that need further study.
