Artificial aging control of aluminum alloys

摘要

A method of artificially aging an aluminum alloy product to achieve a property in the product having the steps of aging the product to achieve the property by heating the product over an aging period, the aging period including a time period where the product is in an underaged state, and terminating the heating when the property is achieved according to a mathematical formula. The property is calculated as a function of time and product temperature measured over the aging period. Calculation of the property includes integration of the thermal effects on the product over the entire aging period including during the time period of underaged product state.
