Crystallographic classification of special grain boundaries
Abstract
Object of research: Special grain boundaries in centrosymmetric crystals.
The aim of this work is to classify special grain boundaries in centrosymmetric crystals of all syngonies based on the symmetric properties of plane lattices that are the crystallographic planes of these crystals.
Conclusions: It is shown that the set of geometric parameters identifying special boundaries consists of elements of the symmetry of the plane formed by coinciding atoms that preserve the atomic structure of this plane. Possible misorientations of contacting crystals are found depending on the symmetry of the crystallographic plane for different crystallographic syngonies
