Preparation and Properties of Equiatomic Co–Fe–Cr–Mo–W Alloy Powders

Feasibility of producing equiatomic Co–Fe–Cr–Mo–W alloy powders with a particle size distribution ranging from 32 to 160 μm, suitable for additive manufacturing, is examined. It is determined that an increase in the mechanical alloying time from 20 to 30 h reduces the proportion of the iron-based bcc phase and increases the tungsten-based bcc phase proportion. Agglomeration method’s influence on the morphology, yield, and fluidity of target fraction is shown. Fragmented powders obtained by milling exhibit a fluidity of ~30 s/50 g.
