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, conventional casting, etc. These metallurgical processes are mainly used to create details of simple geometry with the need for further machining. The paper 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.
Key words: high-entropy alloy, wire arc additive manufacturing, metal powder cored wire, phase composition, melting.
