摘要：

The aim of this work is a study of creep before and after the action of high hydrostatic pressure (HHP). Occurrence of a baroplastic effect is connected with the effect of HHP treatment on the superplastic deformation mechanism. The factors caused by the action of HHP which affect this mechanis are a change in grain boundary structure and the ease of sliding along boundaries; an increase in dislocation density and facilitation of their sliding; and an increase in vacancy density and more difficult diffusion creep.
