摘要: Abstract This article reviews different studies carried out on the microstructures and oxide–oxide interfaces encountered in directionally solidified eutectics. Depending phase diagram preparation conditions, lamellar, fibrous or three-dimensional network can be obtained. Interfaces between refractory oxides with various structural types (corundum, fluorite, rocksalt, perovskite garnet) are investigated. Orientation relations interface planes reported general features of structure discussed from high-resolution electron microscopy (HREM) studies. The accommodation lattice mismatch at is investigated by geometric analysis HREM images.
