Abstract

Structural changes in KCl and NaCl single crystals were investigated at the initial stage of the high-temperature creep during impeded motion of dislocation in easy-slip systems. The main features of the formation of dislocation structures were studied at the initial stage of rotational deformation, marked by the development of reorientation bands in single crystals. The subsequent process of rotational deformation was also analyzed, as the reorientation bands enlarge and merge and hence, single crystals become polycrystals.
