摘要：
The microstructure of a Zr-1% Nb is studied in a deformation macrolocalization zone during its transformation into a neck. The related dislocation transformations are found to be cyclic, and this cyclicity is accompanied by oscillatory changes in the volumes occupied by different dislocation substructures, the scalar dislocation density, the subboundary density, and periodic relaxation of internal stresses as a result of the decomposition of low-angle subboundaries and dislocation redistribution. © 2011 Pleiades Publishing, Ltd.
