摘要根据O格的概念和不变线应变的性质，分析了含有不变线的界面失配。提出了满足O线存在条件的最佳取向关系。相应的惯习面将包含O线，并且惯习面中的失配将完全由单组位错容纳。引入了有效不变线的概念。以Zr-2.5wt%Nb合金为例，介绍了寻找最佳取向关系的方法。还提供了惯习面中的相应界面结构。
Abstract Mismatch in interfaces containing an invariant line is analysed on the basis of the O-lattice concept and the properties of the invariant line strain. An optimum orientation relationship is proposed to satisfy the requirement for the existence of the O lines. The corresponding habit plane will contain the O lines, and the mismatch in the habit plane will be accommodated completely by a single set of dislocations. The concept of an effective invariant line is introduced. An example is given for a Zr-2.5 wt% Nb alloy, showing the method of search for the optimum orientation relationship. The corresponding interfacial structure in the habit plane is also provided.
