Powder Welding Wire of High-Entropy Alloying System Cantor for Surfacing

Abstract

High-entropy alloys, consisting of five or more basic elements in equimolar ratios, such alloys may contain basic elements with a concentration of each element from 5 to 35 at.%. This leads to the creation of many alloy systems with simple crystalline structures and extraordinary properties. Such alloys have great practical value and are usually made by powder metallurgy, con-ventional casting, etc. These metallurgical processes are mainly used to cre-ate details of simple geometry with the need for further machining. The pa-per proposes a new method of obtaining a high-entropy alloy of the Cantor alloying system by means of wire arc additive manufacturing (WAAM) using metal powder cored wire. Features of manufacturing high-entropy alloys by alternative methods are considered, and the advantages of using WAAM are emphasized.
