Abstract：

In order to investigate mechanical properties and electromagnetic forming properties of 2B06 aluminum alloy used in aviation region under different strain rates, the mechanical performance tests and electromagnetic bulging and flanging tests under different strain rates were conducted. The results show that the ductility of the sheets under two heat-treated states is significantly enhanced with the increasing of strain rate, and the ductility of the T-state sheet is still lower than that of the O-state sheet even at higher strain rates. Subsequently, electromagnetic bulging and electromagnetic flanging tests with specific features were carried out based on the platform of electromagnetic forming, and the forming laws of 2B06 aluminum alloy under different heat treatment states were analyzed by measuring die fitting gap, thinning and hardness. Among them, the bulging and racetrack-shaped flanging features had the transition areas of rounded corners and straight wall, which showed more complicated forming behaviors, larger fitting die gaps and serious thinning. Especially in the process design of the T-state sheet with lower ductility, they needed to be focused on.
