Abstract
Disclosed herein are embodiments of mechanically alloyed powder feedstock and methods for spheroidizing them using microwave plasma processing. The spheroidized powder can be used in metal injection molding processes, hot isostatic processing, and additive manufacturing. In some embodiments, mechanical milling, such as ball milling, can be used to prepare high entropy alloys for microwave plasma processing.

A method for manufacturing a spheroidized powder from a mechanically alloyed feedstock, the method comprising:
- introducing a mechanically alloyed feedstock into a microwave plasma torch, a plasma plume of the microwave plasma torch, and/or an exhaust of the microwave plasma torch, the mechanically alloyed feedstock prepared by milling a plurality of elemental powders or pre-alloyed powders;
- and
- contacting the mechanically alloyed feedstock with a plasma within the microwave plasma torch, the plasma plume of the microwave plasma torch, and/or the exhaust of the microwave plasma torch to form spheroidized powder, and
- wherein the mechanically alloyed feedstock comprises TiZrNbTaFe, AlFeVSi, FeCoNiCrTi, FeCoNiCrAl, or FeCoNiCrCu.
A method for manufacturing a spheroidized powder from a mechanically alloyed feedstock, the method comprising:
- introducing a mechanically alloyed feedstock into a microwave plasma torch, a plasma plume of the microwave plasma torch, and/or an exhaust of the microwave plasma torch, the mechanically alloyed feedstock prepared by milling one or more powders to form an alloy comprising an entropy of mixing of greater than about 1.67R;
- and
- contacting the mechanically alloyed feedstock with a plasma within the microwave plasma torch, the plasma plume of the microwave plasma torch, and/or the exhaust of the microwave plasma torch to form spheroidized powder, and
