  • Method for producing metal powders
    Patent number: 5328500
    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.

  • Soft composite metal powder and method to produce same
    Patent number: 4799955
    Abstract: Disclosed is a composite metal powder made from a base iron powder milled with an alloying component such as nickel, copper, managnese, chromium, silicon, phosphorus, boron, vanadium, and molybdenum, where the composite metal powder has a compressibility comparable to the compressibility of the soft base iron powder prior to milling. Such a composite is obtained by using a short mill time followed by an annealing step.
