摘要：

The effects of additional alloying components in Al-Cu-Mg alloys on precipitate coarsening kinetics are explored. Additions of Cr and Ni are shown to have a positive effect on the stability of the S precipitate, while additions of Li and Si significantly increase the coarsening rate. The analysis presented here is generic in nature and may easily be extended to other alloy systems. (C) 2005 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
