Abstract

A method for producing a heat-treated aluminum alloy casting in a shortened period of time, the method comprising: (a) providing a heat treatable aluminum alloy casting at a solutionizing temperature; (b) first stage cooling the heat treatable aluminum alloy casting to a critical temperature at which precipitation of second phase particles of the heat treatable aluminum alloy casting is negligible, wherein the first stage cooling comprises a first stage cooling rate from about 15°F per second to about 100°F per second; (c) second stage cooling said heat treatable aluminum alloy casting to ambient temperature; (d) heating said heat treatable aluminum alloy casting to an artificial aging temperature; and (e) artificially aging said heat treatable aluminum alloy casting at said artificial aging temperature for a predetermined artificial aging time to form said heat-treated aluminum alloy casting.
