Chapter 8 Effect of alloying elements on the phases of high-entropy alloys

High-entropy alloys (HEAs) are acclaimed for their remarkable properties like high strength, high temperature strength, corrosion resistance, irradiations, etc. These properties are realized due to the synergic effect of constituent alloying elements of HEAs, and the end-effect of alloying element is obtained as the phases or microstructure formation of HEAs. The properties of HEAs are the function of phases. Thus, this chapter deals with the influence of alloying elements and their variations on the phases or microstructure of HEAs. It also elucidates the research gaps in the past literature, which would enable the researchers to design tailored HEAs with desired properties.
