摘要
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 itcan purify the interface between binder phase and carbide phase, and increase the thickness of rimphase slightly. The effect is in the most evidence when the mass fraction of Y is 0.8 percent andwhen the transverse rapture strength and the hardness of Ti(C, N)-based cermet are maximal.
