摘要：

Cu segregation was detected at the Q'/alpha-Al interface in an Al-Mg-Si-Cu alloy by energy-filtered transmission electron microscopy. By contrast, in a Cu-free Al-Mg-Si alloy no segregation was observed at the interface between the matrix and Type-C precipitate. (C) 2002 Acta Materialia Inc. Published by Elsevier Science Ltd.
