SiC particle reinforced 2124 aluminum alloy composite sheet was studied on high strain rate superplastic forming into three types of bead panels. The forming test was performed at 773 K using a 250 mm × 250 mm blank sheet by gas pressure, which was preset to achieve the average strain rate of 0.1/s. Three shapes were successfully formed in about 10 seconds and the formability into three-dimensional shapes were confirmed under high forming rate. In case of a box shape or a box shape with a shallow bead at the bottom, minimum thickness was seen at four corners of the box. For the multi narrow deep bead panel, however, it was seen at the side wall near the flange and the maximum thickness strain was 150 to 200%. The simple prediction method of gas pressure pattern used in this study is applicable to certain complex shapes.
