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.
