摘要：
Mechanical spectroscopy and electrical resistivity measurements were performed on QE22 alloy. A new damping peak at around 530 K, at a frequency of about 1 Hz, promoted by the precipitation of semicoherent and incoherent precipitates was discovered. The activation energy of the precipitation process was also obtained. (C) 2004 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
