Textures and local orientations have been determined in copper alloys after cold rolling and annealing. The measurements show that for a strain below a given threshold a mixed "deformation-recrystallization" texture is obtained after a static primary recrystallization: the {100} cube orientation becomes stronger as annealing procedes, but is not dominating in the final microstructure. Global texture determinations by X-ray diffraction coupled with local orientation measurements by EBSD (Electron Back-Scattered Diffraction) show that in materials cold rolled by 70 and 80 percent, the orientation changes at the very beginning of the recrystallization process (i.e. at nucleation) are crucial for the formation of the recrystallization texture.
