The use of zinc sheets has largely increased in the last years, fundamentally because of new tendencies in architecture and, at the same time, due to its excellent properties, as corrosion resistance under aggressive climatic conditions, malleability, recyclability, and surface finishing aspect. In the present work, the X-ray diffraction technique is used to characterize the crystallographic texture evolution of a strongly anisotropic Zn20 zinc sheet (Zn-Cu-Ti) subjected to uniaxial tension, plane strain, and equibiaxial tension, for specimens cut at 0, 45, and 90 deg with respect to the rolling direction. The crystallographic texture evolution is evaluated by means of pole figures, orientation distribution function, and Kearns factors. For all tested strain paths, deformation produces a decrease in the intensity of the crystallographic textures, due to a dispersion of the orientations of the different axes around the initial maxima.
