High-Entropy Alloys and their Production Via Combustion Synthesis

Abstract

This paper describes a summary of the basis of high-entropy alloys (concept, physical metallurgy, properties, production routes, and application prospects) with some examples that indicate their production by combustion synthesis processes. High-entropy alloys (HEAs), are a relatively new group of alloys, have become one of the most interesting subjects among scientific studies due to their superior properties. The properties of HEAs are affected by their constituents and the production routes. Combustion synthesis is one of the production methods which is used to synthesize both high-entropy alloys and high-entropy compounds, such as oxides, carbides, etc. The results of some of the experimental studies about the CS process applied to the production of HEAs and their compounds were given in the concept of this study
