It was recalled that, during plastic deformation, dislocation boundaries appeared which separated regions having differing orientations. The occurrence of disorientations across these boundaries was considered here for several types of boundary. A statistical theory of disorientations was developed for incidental dislocation boundaries. Deterministic contributions which arose from geometrical factors were taken into account for geometrically necessary boundaries. A resultant diversity of the predicted boundary behaviours explained experimentally observed differences in the dependence of the average disorientation angle upon plastic strain.
