Abstract

The substructure inhomogeneity of real textured metal materials was studied by use of recently developed methods of X-ray diffractometry and data treatment. Main regularities of substructure inhomogeneity were revealed for the first time by the analysis of generalized pole figures. The structure of deformed metal includes an extremely wide spectrum of substructure conditions. The crystallographic orientation of grains is the most effective criterion for systematization of substructure inhomogeneities in textured materials. The dispersity of grains and the distortion of their crystalline lattice are minimal in texture maxima and increase up to highest values by passing to texture minima. The distribution of lattice elastic deformation in rolled metals most often shows a cross-wise pattern, consisting in alternation of quadrants with predominance of elastic extension or elastic compression.
