Prospect of high entropy alloys (HETAs) for advance application

Abstract

Presently, HETAs are of enormous research significance in material engineering and sciences. In contrast to the traditional alloys with one and occasionally two base constituents, high entropy alloys consist of many essential elements, which are considered in excessive number compared to the conventional alloys. The arrival HETAs ignites some basic questions that challenge the hypothesis, mock-up, and preparation techniques of the traditional alloys. Here, the review of the latest studies on the prospect and essential subjects related to HETAs were provided. Besides, the novelty in the characteristics of high entropy alloys were also examined, which includes: high wear and corrosion resistance, outstanding mechanical behaviour at high temperature, superb service strength, and ductility, exceptional fracture toughness at extremely low or cryogenic temperatures, super-conductivity and super-paramagnetism. As a result of their richness of design, great structural and operational potential, they are now seen as promising materials for novel and advance applications, which should be further investigated.
