Abstract

The feasibility of producing high-strength/high-formability Al alloy sheets using a technique that combines twin-roll strip casting and asymmetric rolling is reported. An Al alloy sheet with the nominal composition of Al-1.0Si-0.6Mg (in wt%) produced in this study exhibited an excellent formability (r=1.20, and δr=0.17) and mechanical properties (σTS~265MPa, ε~35%), which cannot be feasibly obtained via the conventional technique based on direct-chill (DC) casting and repetitive rolling. The structural origin of the enhanced formability was explored by examining the evolution of textures associated with the strip casting and subsequent thermo-mechanical treatments and interpreted using the viscoplastic self-consistent (VPSC) model.
