摘要：
Embodiments of the present invention include methods of producing a composite article. A method comprises introducing a first powdered metal grade from a feed shoe into a first portion of a cavity in a die and a second powdered metal grade from the feed shoe into a second portion of the cavity, wherein the first powder metal grade differs from the second powdered metal grade in chemical composition or particle size. Further methods are also provided. Embodiments of the present invention also comprise composite inserts for material removal operations. The composite inserts may comprise a first region and a second region, wherein the first region comprises a first composite material and the second region comprises a second composite material.
