When aluminum is ironed, it almost compressively flows like a hot liquid down the wall of the die cavity and punch, and it shines to a mirrorlike surface

SPRINGBACK ANALYSIS OF SHEET METAL LAMINATES

However, for sheet metal laminates consisting of dissimilar metal components, the springback behavior is much more complicated than for monolithic sheets [1]. Hino et al. [11] pointed out from the numerical simulations of uniform stretch-bending that higher stretching force does not always reduce the springback of sheet metal
