Abstract

Material behavior of Al5754 was characterized using both tensile and hydraulic bulge tests under both room and warm temperature conditions. Response of Al5754 to different process conditions such as pressurization rates (0.022 and 0.2s-1 strain rate), variable strain rates (increasing and decreasing profiles), forming temperature (room to 260°C), and loading conditions (uniaxial vs. biaxial) were presented. The results from tensile and hydraulic bulge tests as well as closed-die hydroforming experiments suggested that, in general, formability of Al5754 could be improved with slow forming rates (<0.02s-1), high forming temperature (>200°C), and biaxial loading (hydoforming) due to the delay of necking. However, decreasing forming rate conditions did not show any improvement in formability for temperature levels below 200°C.
