摘要：
Superior superplastic ductility of 2300% was achieved at 520 degrees C and. = 5.6 x 10(-2) s(-1) in an Al-5%Mg-0.2%Sc alloy produced by traditional chill casting followed by cold rolling with a total reduction of 80%. (c) 2006 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
