摘要：
An ultrafine-grained Al-Mg alloy was synthesized by the consolidation of cryomilled powders and subsequent hot extrusion. At strain rates of 10(-4) and 10(-3) s(-1), the stress-strain curves show the serrated-flow behavior. At strain rates of 10(-2) and 10(-1) s(-1), instead of the serrated flow, the shear band formation was observed. (C) 2005 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
