Texture and mechanical properties of a superplastically deformed Mg–Al–Zn alloy sheet

The texture and tensile properties of a fine-grained Mg–Al–Zn alloy sheet at room temperature prior to and following superplastic deformation were examined. The pre-existing basal texture of the sheet drastically weakened after superplastic deformation, and thus the geometric conditions for basal slip, characterized by the Schmid factor distributions, became more favorable. Consequently, relatively high ductility was maintained after superplastic deformation in spite of cavity formation.
