| 摘 要： | 对Ｔｉ（Ｃ，Ｎ）基金属陶瓷的相界面过渡层进行了系统的研究．实验结果表明：金属陶瓷中Ｔｉ（Ｃ，Ｎ）硬质相周边存在明显的包覆层组织，它是一种过渡相；Ｔｉ（Ｃ，Ｎ）／Ｎｉ相界面没有固定的取向关系；Ｗ，Ｍｏ元素主要富集于相界面，且Ｔｉ，Ｎｉ，Ｗ，Ｍｏ元素在相界面具有成分梯度高分辨电镜观察发现，相界面过渡层厚约８－１０ｎｍ并由纳米晶组成．这种过渡层是金属陶瓷的一种比较理想的相界面结构．

| Abstract: | The phase interfacial transition layer in Ti(C,N)-based cermet has been proved systematically by using TEM and EDAX.Experimental results show that there exist obviously a surrounding structure at the edge of carbonitride phase in Ti(C,N)-based cermet,it is a transitional phase.Ti(C,N)/Ni phase interface has no constant orientation relationship.W and Mo are basically concentrated in interface and there is a composition gradient of Ti,Ni,W and Mo in phase interface.HREM observation of interface reveals that in phase interface of Ti(C,N)-based cermet,the transitional layer has width of 8-10 nm and nanocrystalline structure. |
