Аннотация The main idea was to determine the conditions of macro- and micro-defects formation in single crystals of large diameter grown by the Czochralski method. It was found that the value of the average density of dislocations in the crystal cannot be regarded as a definite criterion of origin or absence of the substructure. It was consider that the small-angle boundaries are the result polygonisation occurring mechanism slip or climb of dislocations in the crystal growth zone, closely related to the crystallization front. These boundaries can reach the solidification front, after which they inherited a growing crystal, forming macroblocks oriented along the growth axis.
