Effect of Processing Route on the Phase Evolution of High Entropy Alloys: A Review

Saket Kumar | Manoj Chopkar

Abstract: High entropy alloys (HEAs) are playing great role in material industry. The unique composition of HEAs results in a high degree of structural complexity, which can lead to enhanced mechanical, physical, and chemical properties. These alloys can be prepared with various processing routes. This article presents various processing techniques for CoCrCuFeNiSi (cobalt chromium copper iron nickel & silicon) based HEAs. The processing routes can be majorly categories into meting and casting (liquid state), powder metallurgy (solid state) and films (gaseous state).The specific technique used will depend on factors such as the desired alloy composition, the intended application, and the desired properties of the final product. The addition of Si can obviously improve the micro-hardness and wear resistance of traditional materials. This article discusses about the different processing routs suited for CoCrCuFeNiSi based HEAs.

Keywords: High entropy, multi-principal elements, processing routs, strengthening mechanism
