Abstract
Recent progress in understanding the origins of hardening in Al-1.7Cu- 0.01Sn (at. %) and Al-1.1Cu-1.7Mg-(0.1 Ag, 0.3-0.5Si) (at. %) microall oyed alloys is presented. The results of systematic studies involving atom probe field ion microscopy in conjunction with transmission elect ron microscopy indicate that the precipitation processes depend to a c onsiderable degree upon the nature of pre-precipitate clustering react ions which occur early in the decomposition of the solid solution. Fur thermore, it is shown that the presence of these co-clusters can influ ence significantly the alloy properties.
