摘要
Embodiments of a method for non-isothermally aging an aluminum alloy are provided. The method comprises heating an aluminum alloy at a first ramp-up rate to a maximum temperature below a precipitate solvus value, cooling the alloy at a first cooling rate sufficient to produce a maximum number of primary precipitates, cooling at a second cooling rate until a minimum temperature is reached wherein the growth rate of primary precipitates is equal to or substantially zero, and heating the alloy at a second ramp-up rate to a temperature sufficient to produce a maximum number of secondary precipitates.
