Abstract
Typical configurations of broken dislocation boundaries formed during plastic deformation at faceted grain boundaries have been analyzed. The reasons for their formation have been determined. It has been shown that the shape and sizes of strain-induced broken dislocation boundaries can be determined by the geometry of a faceted boundary and the relevant slip systems of lattice dislocations. The calculations carried out in the framework of the 2D model make it possible to explain the morphology of the observed broken dislocation boundaries.
