Interfacial Reaction and Effect of SiCf/Ti-6Al-4V Composites
摘 要
采用扫描电镜和透射电镜研究了SiCf/Ti-6Al-4V复合材料的界面反应,并借助纤维顶出试验和有限元方法,分析了界面反应层厚度对界面剪切强度和残余热应力的影响.结果表明: SiCf/Ti-6Al-4V复合材料界面反应产物主要为TiC,其又分为二层,晶粒较粗大的TiC层靠近基体钛合金,晶粒细小的TiC层靠近SiC表面的碳涂层;随着反应层厚度的增加,界面抗剪强度提高,纤维和反应层内的径向残余热应力有所增大,反应层内的环向残余热应力分布有所改变.

Abstract
The interfacial reaction of Ti-6Al-4V composites reinforced with SiC fibers was investigated by means of scanning electron microscopy and transmission electron microscopy.Effect of interfacial reaction layer thickness on the interfacial shear strength and thermal residual stresses were analyzed by push-out test and finite element modeling respectively.The results indicate that the interfacial reaction of the SiCf/Ti-6Al-4V composites formed two layers of TiC,and one with larger grains located adjacently to the Ti-6Al-4V matrix and the other with finer grains closed to the carbon coating.With the increase of interfacial reaction layer thickness,the interfacial shear strength of the SiCf/Ti-6Al-4V composites increased.The radial thermal residual stress in the fiber and interfacial reaction layer increased slightly,and the hoop thermal residual stress in the interfacial reaction layer changed slightly.
