Abstract
A method for heat treating cast aluminum alloy components that includes obtaining a casting formed from an aluminum alloy having a silicon constituent and at least one metal alloying constituent, and heating the casting to a first casting temperature that is below but within 10° C. of a predetermined silicon solution temperature at which the silicon constituent rapidly enters into solid solution. The method also includes increasing the rate of heat input into the casting to raise the temperature of the casting to a second casting temperature that is above but within 10° C. of a predetermined alloying metal solution temperature at which the at least one metal alloying constituent rapidly enters into solid solution, maintaining the casting at the second casting temperature for a period of time that is less than about 20 minutes, and then quenching the casting to a temperature less than or about 250° C.
