摘要：
In this paper we analyze mesodefects accumulating during plastic deformation on the faceted high angle grain boundaries. It is shown that the system of mesodefects can be represented as a set of linear mesodefects of the rotational type (junction disclinations), and planar mesodefects of the shear type (uniformly distributed dislocations with Burgers vector lying in the plane of the facet). The process of formation of broken dislocation boundaries in the elastic fields of various configurations of the abovementioned mesodefects is studied within the framework of computer simulation.
