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. 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.
