Thesegregation induced structural transformations from one structure to another accom-panying with the displacement of the upper grain in respect to the lower grainand the migration of the grain boundary plane have been observed. A shear mecha-nism has been proposed in order to explain such foundings on basis of the grainboundary structural unit model and the structural multiplicity.
