摘要：
The microstructural evolution and ageing behaviour of Al-4.0Mg-1.5Cu-1.0Li-(0.2Sc)-0.12Zr alloys were investigated. The results indicate that small addition of Se can enhance the ageing strengthening effect while the time taken to the ageing peak is prolonged. And the Sc-containing Al-4.0Mg-1.5Cu-1.0Li-0.2Sc-0.12Zr alloy exhibits a promising combination of strength and ductility. TEM observations show that the precipitation processes during ageing can be modified by the small addition of Sc. (C) 2003 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
