ABSTRACT:
A powder metal composite made up of first and second powder metal bodies assembled in a mold cavity with the bodies separated by a divider ring and with the bodies being in concentric relationship such that the assembled bodies and divider ring can be simultaneously compacted and subsequently simultaneously sintered to form the desired composite metal article. In practicing the method of forming a composite metal article one of the bodies may be selected from a base powder metal and the other body may be selected from a high performance alloy powder metal, and the divider ring may be selected from a low melting point metal such as copper that will dissolve itself into the powders during sintering and enhance mechanical properties of the sintered compact article. The composital metal article may be used as it is if the density for its intended uses is satisfactory, or such article may be further densified by being subjected to an additional hot forging operation with the article sintered thereafter if deemed necessary.
