Abstract

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.
