Effect of alloying elements on the properties of high-entropy alloys

High-entropy alloys (HEAs) consist of five or more major alloying elements, resulting in outstanding characteristics, namely, compressive strength, high temperature strength, and hardness. For a wide range of applications, specific properties such as, compressive strength and strain, tensile strength and strain, and hardness, or their combinations are necessary. However, it also noticeable that achieving a balance of properties (like strength and ductility) in HEAs is still a big hurdle for its wide application. Therefore, this chapter emphasizes on the influence of alloying elements on the properties of HEAs, which would enable researchers to design HEAs with the desired attributes for specific applications.
