Abstract :
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.
