In order to study the distribution of lattice elastic microstresses in textured metal materials, pole figures of X-ray line peak position were constructed on the basis of data, obtained by diffractometric texture measurements using a position sensitive detector. The data treatment involves recalculation of the Bragg angle 2θϕψ into the relative deviation of the interplanar spacing from the weighted average level Δd/dav. Depending on the texture character, different modes of microstress equilibrium take place. A common feature of most lattice deformation pole figures is the cross-wise pattern, consisting in alternation of quadrants with predominance of lattice elastic extension and compression. In cases of simple rolling textures, the microstress equilibrium is attained by some additional ways, among which there are breaking of texture maxima into halves with opposite signs of elastic deformation, predominance of one-sign elastic deformation within different texture maxima, development of stretched zones with opposite signs of elastic deformation at slopes of texture maxima. In some cases the identical microstress distribution in all quadrants of pole figure is observed.
