摘要：
Fine-grained ZK60 magnesium alloy with the grain size of 1.4 mum was processed by equal-channel-angular extrusion. The material exhibited low temperature superplasticity. The normalized plot suggested that the present material had equilibrium grain boundaries at the superplastic temperature in contrast to typical materials processed by severe plastic deformation.
