Abstract: The forming limit and springback behavior of Al-Cu-Sc heat-resistant aluminum alloy for thin-walled curved parts are investigated by notched specimen tensile and curved specimen stretch-forming tests. Results show that with the decrease of notch radius, the deformation state of the specimen can transform from uniaxial tension to plane strain, with the strain ratio |ε2/ε1| decreasing from 0.40 to 0.06, the forming limit strain decreasing from 0.219 to 0.084, and the fracture strain decreasing from 0.146 to 0.109. The deformation uniformity of the curved specimen is better than that of the rectangular specimen. Compared with the directly formed from T6-tempered sheets, the W-tempered sheets with stretch-forming and aging treatments has similar mechanical properties with the T8-tempered sheets, and the deviation of the notch radius of the W-tempered sheets and the target value is only 2.4%, indicating that the aging treatment has slight effect on the forming precision. This study offers theoretical support for the high-precision forming of unmanned equipment curved skins.
