The effect of RE element Y on the microstructure and properties of Ti(C, N)-based cermet has been investigated.Yttrium can refine the particles of carbide phase because it can purify the interface between binder phase and carbide phase,and increase the thickness of rim phase slightly. The effect is in the most evidence when the mass fraction of Y is 0.8% and when the transverse rupture strength and the hardness of Ti(C, N)-based cermet are maximal.
