Cemented carbide - metallic alloy composites

A method of making a composite sintered powder metal article, comprising:

• providing a first powder in a first region of a mold, the first powder comprising hard particles and a powdered binder;
• providing a second powder in a second region of the mold, wherein the second powder contacts the first powder and comprises at least one of a metal powder and a metallic alloy powder selected from a steel powder, a nickel powder, a nickel alloy powder, a molybdenum powder, a molybdenum alloy powder, a titanium powder, a titanium alloy powder, a cobalt powder, a cobalt alloy powder, a tungsten powder, and a tungsten alloy powder;
• consolidating the first powder and the second powder in the mold to provide a green compact;
• and
• sintering the green compact to provide a composite sintered powder metal article comprising a cemented hard particle region formed from the first powder and metallurgically bonded to a metallic second region formed from the second powder.
