To assess the effect of texture changes on the activation of slip systems, a systematic analysis of the slip traces after uniaxial tension of ECAP processed samples at room temperature was carried out. The analysis reveals the profuse activation of additional slip systems than the common basal <a> slip and pyramidal II <c+a>, where non-basal slip such as prismatic <a>, pyramidal <a> and pyramidal I<c +a> played a major role than expected in the rolled sheet. The relative activity of deformation mechanisms was significantly changed in the ECAP processed sheet, where extension twinning, basal <a>, pyramidal I <c+a> and pyramidal II <c+a> slip dominated the deformation.
