Abstract: Nowadays, the increasing requirements for energy conservation and emission reduction have fostered the application of the hot-stamped aluminum alloy for lightweight. However, it is difficult to achieve industrialized production because of the long-term process as well as high production costs. In this study, a hot stamping process for aluminum alloys based on short-wave infrared heating is presented. To enhance the absorption of short-wave infrared rays, the emissivity was increased by nano-graphite coating, it greatly improved heating efficiency. U-shaped parts with different forming depths (20~60mm) were successfully prepared in 5052 aluminum alloy, and the larger strain in the sidewall region of the U-shaped parts resulted in higher strength and hardness. The increased deformation promotes dynamic recrystallization, the grain morphology shifts to equiaxed recrystallized grains, and a large number of low-angle grain boundaries are retained within the grains, indicating that dynamic recovery dominates the deformation mechanism.
