摘要：
Excellent low-temperature superplasticity (<300 degreesC) was observed in the ECAP-processed materials: elongations to failure are 810% and 570% at a strain rate of 3 x 10(-3) s(-1) for ZK60 and AZ91 alloys, respectively. Internal friction can be practically used to determine the optimum temperature for superplasticity. (C) 2003 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
