Study on Microstructure, Mechanical, and Thermal Properties of High-Entropy Alloys

The research focus in almost all applications is currently high-entropy alloys (HEAs). HEAs comprise several main elements which can extend considerably more than conventional alloys by the possible number of HEA compositions. Different alloy structures with improved property combinations have been explored in the last 15 years to identify HEA systems, resulting in an extraordinary development of this area. This paper discusses a few essential topics in the field: core effects, phase development, mechanical features, high temperature, and corrosion behavior. It also outlines existing issues and future recommendations for product technology and research.
