PROCESS CONTROL-EVALUATION OF ALCOA'S NEW ARTIFICIAL AGING TREATMENT FOR 7079 ALUMINUM ALLOY

Abstract

The two step aging treatment can be applied immediately after quenching from the solution heat treatment temperature, or after stretching or forming in the 7079-W temper and produce mechanical properties comparable to those obtained using the present aging treatment. This new procedure can be considered as an alternate to the practice described in MIL-H-6088B. Data on time delay between solution heat treatment and artificial aging of 7075 and 7178 is included. Immediate artificial aging of aluminum alloys, 7075 and 7178, does not produce marked differences of mechanical properties as compared with one, five, or ten day delay. (Author)
