As AlMgSc sheets cannot be stretch formed at room temperature due to cracking in the clamping zones, an alternative technology called ""creep-forming"" was investigated by Jambu [2]. Nevertheless, creep-forming is only applicable for panels to be formed in moulds with small curvatures, because shaping double-curved geometries with small radii of curvature tends to buckling [3]. Hence, the formability of large spherical aluminum sheets as double-curved geometries is investigated.enmaterial formingaircraftamorphous metalconference paper
