Improving a mechanical property of a heat treatable aluminum alloy by heat treating the aluminum alloy, cooling the heated aluminum alloy, pre-aging the cooled aluminum alloy, and aging the pre-aged aluminum alloy

摘要

Improving a mechanical property of a heat treatable aluminum alloy comprises: (a) heat treating the aluminum alloy at a solution treatment temperature for the aluminum alloy for a first period of time; (b) heating the heat treated aluminum alloy to a temperature of 5-30[deg] C above the solution treatment temperature; (c) cooling the heated aluminum alloy; (d) pre-aging the cooled aluminum alloy at room temperature to 100[deg] C; and (e) aging the pre-aged aluminum alloy at an aging temperature above the pre-aging temperature.
