摘要：

Superplasticity of coarse-grained magnesium alloy has been investigated. Elongation of 320% has been obtained at 773 K and a strain rate of 1 x 10(-3) s(-1). The grains were refined from initial 300 to 25 mum when the stress reached its maximum. The grain size maintained about 25-30 mum dynamically in the proceeding deformation. Mechanical behavior and microstructures have also been studied. (C) 2002 Acta Materialia Inc. Published by Elsevier Science Ltd. All rights reserved.
