Abstract

In this paper, Ti-48Al-2Cr-2Nb (at. %) gamma-based alloy spherical powders were prepared by mechanical alloying of elemental powders and plasma spheroidization. Microstructural features and phase composition of the obtained powders were studied after different time of mechanical alloying in a planetary mill to investigate the alloy formation. After determining optimal milling parameters allowing to obtain powders with a fairly homogeneous microstructure and composition, the powders were treated in the flow of a thermal plasma to produce powder particles with a high degree of sphericity. The produced spherical powders were investigated using Scanning Electron Microscopy and X-Ray Diffraction. The study showed the feasibility of the suggested approach to fabricate spherical homogeneous powders of gamma-based intermetallic alloy for its application in Additive Manufacturing processes.
