A pulse-current-assisted age forming process of the Al alloy component is developed and evaluated by simulation and experiments. The effect of pulse-current on the electric current density distribution, Joule heat effect, springback, mechanical properties, and precipitation microstructure of a 2219 Al alloy plate component is investigated. The results show that the current distribution is centrosymmetric in the component and the Joule heat effect under the low-density pulse current (less than 80 A/cm2) can be ignored. Compared with the traditional age forming process, the pulse-current-assisted age forming process can reduce the springback and the shape deviation. This should be related to the pulse-current promotion of dislocation movement. At the same time, it restrains the coarse θ′ phase precipitation and homogenizes the precipitate distribution. Therefore, both the mechanical properties and electrical conductivity are increased evidently. Therefore, the pulse-current-assisted age forming process can improve the forming efficiency and precipitate microstructures, as well as the comprehensive performance, making it a potential cooperative manufacturing technique for better control of the shape and performance of high-strength aluminum alloy components.
