摘要

基于平面晶格的对称性质，对所有晶体学体系中中心对称晶体的特殊晶间边界进行了分类。结果表明，识别特殊边界的取向参数集是由接触晶体的匹配原子形成的平面的取向决定的。与一般类型的边界不同，这些参数的数量是两个或三个。结果表明，匹配双晶节点的晶格只出现在具有高阶对称轴的晶体中。根据不同晶体条件下晶体平面的对称性，发现了接触晶体可能存在的取向偏差。

Crystallographic Classification of Special Intercrystallite Boundaries

A classification of special intercrystalline boundaries in centrosymmetric crystals of all crystallographic systems is constructed based on the symmetric properties of planar lattices. It is shown that the set of orientation parameters identifying special boundaries is determined by the orientation of the plane formed by the matching atoms of the contacting crystals. Unlike for the general type of boundaries, the number of these parameters is either two or three. It is shown that the lattice of matching bicrystal nodes appears only in crystals with high-order axes of symmetry. Possible misorientations of the contacting crystals are found, depending on the symmetry of the crystallographic plane for different crystallographic conditions.
