Abstract

Metal injection molding (MIM) process has an advantage of fabricating three dimensional complex shaped components, which alleviates the need for secondary working operations. Therefore, MIM process is hoped to be a suitable production route for the hard materials such as cemented carbides. This study has been performed to determine the production feasibility of sintered Co-Cr-W-C alloys by MIM process, and the mechanical propertie microstructures. The results obtained were as follows:<BR>(1) An adequate carbon level of the alloy was achieved by solvent debinding followed by final thermal debinding in H₂ and N₂ gas mixtures atmosphere.<BR>(2) Injection molded alloys showed the same microstructure and mechanical properties as those of conventional P/M alloys.
