Crystallographic aspects of macroinhomogeneous plastic flow in single crystals of metals

Various crystallographic aspects of the distribution of strain-localization zones have been studied in single crystals of metals subjected to tensile stresses at different orientations of the tension axes and characterized by different mechanisms of plastic flow (slip of dislocations and martensite transformations). It is shown that the crystallographic orientations of the strain-localization zones (interpreted as the patterns of plastic-flow self-organization) are preserved within the whole deformation process. Some characteristic features of the dynamics of the strain sites are considered.
