An asymmetric cryorolling technique was used to reduce the thickness of an Al–Mg–Si alloy sheet from 1.5mm to 0.19mm. The samples were subsequently aged for 48h at 100°C. The hardness and tensile strength of both rolled and aged sheets increased with the number of passes up to the sixth pass, but the tensile stress decreased after the seventh pass. Investigation of the microstructure of the sheets...
