Abstract
A method for producing a heat treated aluminum alloy product in a shortened period of time, the method comprising: (a) providing a heat treatable aluminum alloy; (b) working the heat treatable aluminum alloy at a solutionizing temperature to form a product; (c) first stage cooling the product to a critical temperature at which precipitation of second phase particles of the heat treatable aluminum alloy 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; (d) second stage cooling the product to ambient temperature; (e) heating the product to an artificial aging temperature; and (f) artificially aging the product at the artificial aging temperature for a predetermined artificial aging time to form the heat treated aluminum alloy product.
