Abstract
Stability upon heating an ultrafine structure with high-angle boundaries obtained by shear deformation under pressure depends on the mechanism of its formation (dynamic recrystallization or work hardening) determined by the temperature-rate conditions of plastic deformation. Dynamic recrystallization does not allow attainment of a thermally stable structure.
