摘要

Pole figures of X-ray line peak position were used in the study of lattice elastic deformation as applied to textured metal materials. Diffractometric texture measurements were carried out by a position sensitive detector. Peak position pole figures were constructed either in units of the Bragg angle 2θ_(φψ) or in units of lattice relative elastic deformation △d/d_(av). Several modes of microstress equilibrium are revealed. In most studied cases the distribution of lattice elastic deformation shows the cross-wise pattern, consisting in alternation of quadrants with predominance of extension and compression. In addition, the mutual arrangement of regions with opposite signs of elastic deformation varies depending on the texture character: breaking of texture maxima into halves with opposite signs of elastic deformation, predominance of one-sign elastic deformation within different texture maxima, stretched zones of elastic extension and compression at opposite slopes of texture maxima. Besides, the identical microstress distribution in all quadrants of pole figure develops in some cases.
