本文综述了定向凝固共晶中的显微组织和氧化物-氧化物界面的研究进展。根据相图和制备条件的不同，可以得到层状、纤维状或三维网状结构。研究了不同结构类型的难熔氧化物(刚玉、萤石、岩盐、钙钛矿和石榴石)之间的界面。报道了取向关系和界面，并从高分辨电子显微镜(HREM)研究中讨论了界面结构的一般特征。通过对高分辨电子显微镜图像的几何相位分析，研究了晶格失配在界面的调节作用。
This article reviews different studies carried out on the microstructures and oxide–oxide interfaces encountered in directionally solidified eutectics. Depending on the phase diagram and preparation conditions, lamellar, fibrous or three-dimensional network microstructures can be obtained. Interfaces between refractory oxides with various structural types (corundum, fluorite, rocksalt, perovskite and garnet) are investigated. Orientation relations and interface planes are reported and general features of the structure of interfaces are discussed from high-resolution electron microscopy (HREM) studies. The accommodation of lattice mismatch at the interface is investigated by geometric phase analysis of HREM images.
