Formability and Bake-Hardenability of Al-Mg-Cu Alloy Sheets by Asymmetric Warm Rolling


Article Preview

In this study, asymmetric warm rolling (AWR) has been applied to improve the formability of bake-hardenable Al-3mass%Mg-1mass%Cu-(Ag) alloy sheets. The T4 sheets by the AWR are superior to those by conventional rolling (CR) in Lankford value and drawability. This improvement is caused by a change in the recrystallization texture to have a predominant orientation close to {111}//ND. The unusual texture for recrystallized aluminum alloy sheets is due to the shear deformation introduced during AWR. The Al-Mg-Cu alloy sheets by AWR have been confirmed to possess combined bake-hardenability and the improved formability. However, the bake-hardening response of the Al-Mg-Cu alloy by AWR is slightly inferior to that of the identical alloy by CR.
