抄録

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. In this study, the effects of MIM processing variations on the mechanical properties and microstructures of WC-16, mass%., Co alloy were investigated. The results obtained were as follows:<BR>(1) It was very difficult to debind completely and control the carbon content by using N₂ gas as the thermal debinding atmosphere after solvent debinding.<BR>(2) An adequate carbon level of the alloy was achieved by thermal debinding in H₂ gas atmosphere, and the sintered alloys showed the finer microstructure and higher mechanical properties compared with those of coventional P/M alloys.
