连续纤维增强金属间化合物基复合材料的成功，包括那些基于铝化物，取决于开发一个优化的纤维/基体界面。本文讨论了金属间化合物基复合材料中纤维/基体界面改性的相关问题。这里讨论的界面问题包括界面反应障碍，界面层，以减少纤维和基体之间的热膨胀系数不匹配的影响，和界面层，以提高纤维/基体结合。各种概念演示与一些当前感兴趣的系统中得出的例子。这些例子包括NiAl/Nb_2Be_（17）复合材料系统的界面反应阻挡层、Ti_3Al/SiC系统中调节纤维/基体CTE失配的界面层以及NiAl/Al_2O_3复合材料中改善纤维/基体结合的界面层。
The success of continuous fiber-reinforced intermetallic-matrix composites, including those based on aluminides, depends on developing an optimized fiber/matrix interface. This paper addresses different issues related to the modification of the fiber/matrix interface in intermetallic-matrix composites. The interface issues discussed here include interfacial reaction barriers, interfacial layer to reduce the effect of coefficient of thermal expansion mismatch between the fiber and the matrix, and interfacial layers to improve fiber/matrix bonding. Various concepts are demonstrated with examples drawn from some of the systems of current interest. The examples include interfacial reaction barriers for the NiAl/Nb2Be17composite system, interface layer to accommodate fiber/matrix CTE mismatch in Ti3Al/SiC system, and interface layer to improve fiber/matrix bonding in NiAl/Al2O3composite.
