N2 - Bulk nanostructured Cu samples with 20 mm in diameter and 1 mm in height were processed by HPT at a pressure of 6 GPa by 10 rotations. Measurements of texture by means of state-of-the-art XRD technique have been achieved in directions parallel and normal to the torsion axis. Local texture measurements were performed by a spot size of 500 μm in steps of 3.5 mm in order to examine the homogeneity of deformation. The texture data were resolved to shear plane and analyzed in terms of ideal shear orientations. At both inner and outer areas of the disc plane typical shear textures are observed. However, the intensity of components of textures at inner areas is higher than that of outer one. These results can be interpreted in terms of dynamic lattice relaxations rather than by heterogeneities in deformation.
