Precipitation-hardening heat treatment can further enhance the characteristics of these alloys [1]. The temperature and duration of the precipitation hardening process have a significant role on the performance of the materials for this purpose. This study investigates the effects of artificial aging heat treatment on the mechanical properties of the AA6082 alloy after flow forming process. The influence of artificial aging temperature and time on the mechanical properties of the 6082 aluminum alloy are analyzed. Tensile testing specimens were machined from parts formed by the flow forming. Heat treatments were performed on tensile testing specimens. Solution heat treatment was applied at 530°C/1h with a heating rate of 10°C/min in the open atmosphere and quenched in a 20%vol PAG containing water bath. Artificial aging was then carried out at temperatures of 177°C and 190°C for 4, 6, 8, 10, and 12 hours, respectively [2]. The results demonstrate that the optimum aging temperature and time for 6082 aluminum alloy after flow forming is 190°C/8h.
