Abstract
The present invention provides metal powder compositions for pressed powder metallurgy and methods of forming metal parts using the metal powder compositions. In each embodiment of the invention, the outer surface of primary metal particles in the metal powder composition is chemically cleaned to remove oxides in situ, which provides ideal conditions for achieving near full density metal parts when the metal powder compositions are sintered.
