Abstract
High-entropy alloys (HEAs) are one of the most promising topics over the past decade. Their unique properties, as for example high-temperature stability and high strength, make them a potential candidate material for many challenging applications, as for example tools, moulds and functional coatings. Within this research a single-phase CoCrFeMnNi HEA was produced by gas atomization and melting processes. The process methods were evaluated by characterizing the material properties (density, microstructure, mechanical properties) of the compacted samples. Furthermore, the stability of the known fcc solid solution phase by progressive variation of the composition as well as the addition of titanium are evaluated after melting.
