Abstract
Spherical powders of CoCrFeNiMnW0.25 high-entropy alloy were obtained from elemental powders by mechanical alloying (MA) at various energy modes followed by plasma spheroidization. Samples obtained from low-energy MA-powders have an inhomogeneous microstructure and phase composition. Samples obtained from MA-powders with homogeneous structures have a high degree of sphericity and chemical homogeneity; the face-centered cubic solid solution represents the phase composition of the powders. The resulting powders can be used in powder-based additive manufacturing technologies.
