ABSTRACT:
A TiCN-based cermet cutting insert superior in toughness with improved wear resistance includes a binding phase and at least two of four hard dispersion phases. One of the two hard dispersion phases includes at least one of a duplex or triplex phase structure with a core of a composite carbonitride solid solution and a single-phase structure of a composite carbonitride solid solution. The other hard dispersion phase includes one of a hard dispersion phase of titanium carbonitride and a hard dispersion phase which includes a single-phase structure of titanium carbonitride.
