The superplasticity of a fine-grained Mg-12Li-1Zn alloy, processed by equal-channel angular pressing (ECAP), was studied by shear punch testing. The strain rate sensitivity index of 0.45 and activation energy of 71 kJ mol(-1) is indicative of a superplastic shear behavior dominated by grain boundary sliding. (C) 2013 Elsevier B.V.
