ABSTRACT:
A method for producing a metal composite powder, such as a high alloy metal composite powder, which includes pretreating the alloying components prior to milling with a base iron powder. A short milling time is used, yielding a metal composite powder which exhibits good compactability, microstructure, controllable flow, post-sintering homogeneity, and offers a more economical production method.
