The reasons for changes in the type of the recrystallizatioin texture depending on particular annealing conditions of a deformed single crystal (110) (210)- (310)[001] in deformed single crystals subject to slow heating is due mainly to the orientation dependence of the critical dimension of nuclei.

This paper deals with a metallographic study of shear and deformation bands, which are formed and developed during rolling and fatigue tests of single crystals and polycrystals of Fe-3% Si. The effect of the initial orientation of the single crystals, dimensions of grains in polycrystals, thickness of the samples and certain rolling factors on the formation of banded structures was analyzed. The effect of these structures on the structure and the texture, which appear in the deformed alloy subject to annealing, was studied too.The obtained data provided a better account of the banded structures and permitted directing ways to control their formation and evolution.

The study of the specific features of the flow of different metal layers at the deformation zone during rolling suggests that a regular banded structure of the material is determined by corrugation of some of its layers subject to strain.
