High Entropy Alloy Towards Functional Materials Application: A Review

Abstract The development of high entropy alloy (HEA) is considered a new bloom area as the ideas open up the exploration of a various multi-disciplinary elements in many applications. It is a novel class of complex materials identified in the phase diagram’s core, and they have been proven to outperform typical alloys. This HEA involves mixing unique combinations of mechanical and functional qualities across an infinite space of alloy composition. It is also possessing a great understanding of the thermodynamic behaviour of the materials which influence greatly their physical and mechanical properties. This review paper aims to open up the possibilities of developing HEA on different types of approaches based on the core effects which is very useful in functional materials applications especially in semiconductor, refractory and many more. However, to obtain this material, the most crucial thing is to understand and develop their synthesising routes of HEA production, which has become the main priority. Therefore, this paper focuses on discussing different metal elements that are commonly used in HEA and few fabrication routes on HEA. Some of recent functional materials based HEA is introduced by their enhance properties compare to conventional alloys.
