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 H<SUB>2</SUB> and N<SUB>2</SUB> gas mixtures atmosphere.<BR>(2) Injection molded alloys showed the same microstructure and mechanical properties as those of conventional P/M alloys.
