| 摘 要： | 对带(B4C C)涂层的SiC纤维增强Ti-153复合材料的界面反应进行热力学分析,并对界面反应层做能谱成分分析及X-射线衍射结构分析.结果表明,界面反应层为TiC,TiB2和TiB相的组合物.采用不同的热压工艺制备复合材料并分别进行拉伸实验及扫面电镜观察,从而得出不同界面结合状态与拉伸性能之间的关系.对经不同时间的热处理具有不同界面反应层厚度的复合材料进行拉伸实验,结果表明,随着反应层厚度的增加复合材料性能下降.

| Abstract: | The interfacial reaction in SiC/(B_4C C)/Ti-153 composite were studied by thermodynamic calculation and reaction products were analysised by EDX and XRD.The results showed that reaction products were TiC,TiB and TiB_2.Tensile strength of composites after different hot pressing process and with different fracture surface was also investigated by tensile test and SEM.The results indicated that tensile strength was affected by the state of interface.Finally,the tensile strength of composite with different thickness of interfacial reaction layer after different heat-treatment process was evaluated,it was found that with increasing of thickness of interfacial reaction layer,the tensile strength of composites declined. |
