The Effect of Forming Pressure on Springback in 2XXX Aluminum Alloys

In the aircraft industry, hydroforming is widely used to form parts using aluminum alloys in tempered condition T-XXXX. Success of this process depends on accurate springback prediction. The magnitude of springback and its variation is high in aluminum alloys in tempered condition T-XXXX. Process and material variability causes variation in springback. Wide range of pressures and press types in hydroforming process attribute to process variability. Forming pressures can be varied to control springback. This study looks at the effect of forming pressure on springback in hydroforming of aluminum alloy 2024-T3 and 2524-T3 in two most popular industrial hydropresses. The study forms the basis for developing a new model for springback prediction in the future.
