获得Ti（C，N）基金属陶瓷微晶化界面过渡层的条件是碳化物相的微晶化及冷却过程中的成分过冷.相界面层微晶结构的形成使金属陶瓷的韧性得到提高，性能稳定性得到改善
The formation mechanism of phase interface-layer with microcrystal structure in Ti(C, N)-based cermet has been discussed. The controlling conditions obtaining microcrystal transition layer should be met:(1) carbide phase microcrystallization, (2) composition undercooling during cooling process. The interface layer with microcrystal structure can improve the toughness, strength and stability of properties of the Ti(C, N)-based cermet.
