    Abstract: This paper employs simple rolling process plus annealing to refine the grain size of magnesium alloy ZK60. This goal is effectively achieved, obtaining grains as fine as similar to 3.7 mu m. Such a specimen shows an elongation of 642%, and its ultimate fracture surface exhibits intergranular separation and significant grain growth. Additionally, the effects of the specimen's geometry and tensile test axis with respect to the rolling direction on superplastic elongation is studied, which has not been done before.
