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