摘要： The present invention provides powder metal compositions and methods of making and using the same. Powder metal compositions according to the invention include base metal particles, a lubricant that transforms from a solid phase material to a viscous, liquid phase material during pressing, and a micronized deformable solid material. The micronized deformable solid material fills at least a portion of the void space between the base metal particles during pressing, which allows at least a portion of the lubricant to migrate as a viscous liquid phase material to the interface between the surface of the green compact and the wall of the mold cavity to provide lubrication that reduces the ejection force necessary to remove the green compact from the mold cavity.
