Wear resistant titanium carbonitride-based cermet cutting insert

摘要

A TiCN-based cermet cutting insert superior in toughness with improved wear resistance includes a binding phase and at least two hard dispersion phases. One hard dispersion phases includes a core of TiCN while the other hard dispersion phases includes a core of a carbonitride solid solution of Ti and one of a V,Hf,Cr, Ta,Nb, Zr, W and Mo.
