采用扫描电镜、透射电镜和x射线衍射仪研究了用中国制备SiC纤维增强的Ti-6AI-4V复合材料的界面反应，发现在SiC纤维的C涂层和Ti-6AI-4V基体之间形成的界面反应产物为细晶粒和粗晶粒的TiC，而无C涂层的SiCf／Ti．6AI．4V的界面反应产物，从SiC纤维到Ti-6AI-4V基体，依次为细晶粒的TiC＋Ti5Si3、粗晶粒的TiC和Ti3SiC2。还测量了界面反应区厚度并讨论了界面反应机理。
The interfacial reaction of Ti-6Al-4V composites reinforced with Chinese SiC fiber was investigated by means of scanning electron microscopy, transmission electron microscopy and X-ray diffraction. The reaction product of TiC with fine grains and large grains was identified between the Ti-6Al-4V matrix and the C-coating of the SiC fiber. However, in the interfacial reaction zone of the SiCf /Ti-6Al-4V composite in which the SiC fiber has no C-coating, from SiC fiber to Ti-6Al-4V matrix, there exist fine grains of TiC+Ti5Si3, large grains of TiC and Ti3SiC2. The thickness of the interfacial reaction zone was measured and the interfacial reaction mechanism was discussed.
