- Abstract
The present work aims to improve strength and stretch formability of rolled AZ31 sheet by two-step twinning deformation, i.e., compression (8%) along the rolling direction (RD) and subsequent tension (5%) along RD. A recrystallization annealing was carried out between two twinning deformations to avoid detwinning. It shows that two-step twinning deformation can form strong c-axis//RD texture and generate profuse crossed twin lamellae in each grain. The former can generate a refinement hardening effect to enhance the strength and the latter can contribute to a high stretch formability at room temperature.
