摘要
Ageing the cubic P phase of a Cu-Zn-Al alloy under a constant applied load, changes its relative stability with respect to the martensite. This alteration is independent of the thermal treatment and arises from the ordered nature of the alloy. (C) 2003 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
