Abstract
A TiCN-based cermet comprises 5-25 weight % of a binder phase mainly composed of Co and/or Ni, the balance being substantially a hard phase and inevitable impurities, the hard phase being mainly composed of carbide, nitride and/or carbonitride and containing at least Ti and W, the cermet having a cross-section microstructure in which the number of Ti-rich particles having an area of 0.02 μm2 or more is 1000 or less per a unit area of 1000 μm2.
