Abstract
Deliberate partitioning of solute elements between the matrix solid
solution and dispersed precipitates in aged aluminium alloys can be facilitated simply by underageing or, less commonly, by adjusting alloy compositions. Although these practices usually result in some reduction in tensile properties, it has been shown that significant improvements may be achieved in creep resistance and fatigue strength. If secondary precipitation is encouraged after underageing, simultaneous increases in tensile properties and fracture toughness are possible.
