中文摘要：

SCS-6 原文如此连续的增强纤维的 Ti-Al 金属间化合矩阵的 composites 被新潮的方法制作然后在在不同条件下面的真空对待热。Theinterfacial 反应动力学和机制被使用 SEM，版本和 XRD 学习。结果证明象 C， Ti 和 Si 那样的反应元素的内容变化出现在界面的反应层，和多层的界面的反应混合物形式。在矩阵的 Alloying Nb 显著地扩散进界面的反应区并且为跟随抛物线的率的一个角色的界面的反应层生长改变活化能。活化能(Q~k ) 并且(k_0 ) SCS-6 SiC/super， alpha_2 和 SCS-6 SiC/Ti_2AlNb 是 317.664 kJ/mol， 175.709 kJ/mol and5.4438 X l0~(-2)m/s~(1/2), 1.44 X l0~(-5)m/s~(1/2) ；分别地，并且散开系数(D_c ) 是大约 10 ~(-18)-10~(-20) m~2/s。SCS-6 SiC/Ti-Al 金属间化合的 composites 有更高的接口相容性和稳定性，这被证实。而且，与 SCS-6SiC/super alpha_2，接口相容性和 SCS-6 的稳定性相比， SiC/Ti_2AlNb 更高是平的。

英文摘要：

SCS-6 SiC continuous fiber-reinforced Ti-Al intermetallics-matrix composites were fabricated by HIP method and then heat-treated in vacuum under different conditions. The interfacial reaction kinetics and mechanism were studied by using SEM, EDS and XRD. The results show that the content fluctuation of reactive elements such as C, Ti and Si appears in interfacial reaction layers, and multi-layer interfacial reaction compounds form. Alloying element Nb in matrix remarkably diffuses into interfacial reaction zone and changes the activation energy for the interfacial reaction layer growth following a role of parabolic rate. The activation energy （Qk） and （k0） of SCS-6 SiC/super α2 and SCS-6 SiC/Ti2AlNb are 317.664 kJ/mol, 175.709 kJ/mol and 5.4438X 10^-2m/s^1/2, 1.44× 10^-5 m/s^1/2; respectively, and the diffusion coefficient （Dc） is about 10^-18--10^-20 m^2/s. It is confirmed that the SCS-6 SiC/Ti-Al intermetallic composites have higher interface compatibility and stability. Furthermore, compared with SCS-6 SiC/super α2, the interface compatibility and stability of SCS-6 SiC/Ti2AINb are even higher.
