Formability Changes of Asymmetrically Rolled AA 3003 Al Alloy Sheets

Abstract

Formability and mechanical properties of metal sheets are related to on their textures. It has been studied to improve the formability and change the texture of the AA 3003 Al alloy sheets after asymmetric rolling. Asymmetrically rolled Al sheets are shown the high intensity of the distorted cube texture, {001}, distorted rotated cube texture, {001}, weak γ-fiber, ND//, {123}, {120} and {120} components. After the asymmetrically rolled AA 3003 Al alloy sheets, the plastic strain ratios of the asymmetrically rolled Al alloy sheets were about 1.7 times higher than those of the initial Al sheets. The variation of plastic strain ratios of the asymmetrically rolled Al alloy sheets could be related to the change of texture components through asymmetrical rolling in AA 3003 Al sheet.
