Texture Evolution of Cold-rolled Al-1.8Cu-0.4Mg-0.4Mn Aluminum Alloy

Al-1.8Cu-0.4Mg-0.4Mn aluminum alloy was cold-rolled with different reductions and the texture evolution was investigated.The results show that textures of the samples initially cold-rolled are typical copper-type but with strong G component which got maximum at 70% reduction.Recrystallization texture after annealing is random.However,weak {001}〈110〉 rotated cube component appeares in the sample which was cold-rolled initially with 50% reduction and heated step by step for annealing and finally cold-rolled with 80% reduction.Copper-type texture appeares in the sample that was cold-rolled initially with 70% reduction,and then processe in the same way mentioned above.But after rapidly heating annealing,the sample with 50% initial rolling reduction and 80% final rolling reduction,have strong {001}〈110〉 rotated cube component.The sample with 70% initial rolling reduction and 80% final rolling reduction have weak {001}〈110〉 rotated cube component.
