Processing, alloy composition and phase transition effect on the mechanical and corrosion properties of high entropy alloys: a review

This paper reviews from the corpus of literatures on high-entropy alloys (HEAs), their mechanical and corrosion behavior as affected by metallurgical factors such as processing technique, composition, phase formation and transition. HEAs are a promising class of alloys which are designed based on the use of multiple component alloying elements in equimolar or near equimolar ratio. There has been surging interest in this class of alloys on account of their unique property range. Their unique metallurgical characteristics, structures, mechanical and corrosion properties, current and potential areas of applications, and suggestions for future research are discussed in this paper.
