摘要：
Effect of Mo2C content on the microstructure and mechanical properties of TiC/TiB2 base cermets was studied by using model cermets with the compositions of TiC/TiB2-(11-17)Mo2C-24Ni (mass%). TiC/TiB2 ratio is set to molar ratio of 57/43 that is quasi-eutectic composition. As a result, maximum transverse rupture strength of 680 MPa was obtained for 13mass%Mo2C content sintered at 1693 K. These cermets achieved remarkable microstructural refinement and still maintained characteristic core-rim structure of the TiC base cermets. These cermets have strong possibility to be an alternative material to cemented carbides by tailoring the composition and elimination of large defects.
