Effects of Cold Rolling Reduction on Deformation Modes in Mg-3Al-1Zn Magnesium Alloy

Abstract:

Activation of different slip and twinning systems in cold-rolled Mg-3Al-1Zn at different thickness reductions was investigated by using orientation distribution function and electron backscattered diffraction techniques. The results show that the activation of slip coincides with the most compressive strain, resulting in little need for deformation twinning. The importance of prismatic slip was reinforced and <c+a> pyramidal slip was not a major deformation mechanism during cold rolling. The crystal texture in the cold rolled samples was weakened by twinning but strengthened by slip.
