Abstract
The texture of an AA 8011 aluminum alloy sheet cold rolled by 95% showed a typical β-fiber, which runs from the copper orientation [C={112}〈111〉] over S [{123}〈634〉] to brass [B={011}〈112〉]. The development of annealing textures depended on annealing temperatures due to the interaction between precipitation and recrystallization. Upon annealing at a low temperature of 275°C, precipitation took place before recrystallization. This led to a weak recrystallization texture consisting of {011}〈122〉, {001∼〈100〉, and {hk0}〈001〉, among which the {011}〈122〉 orientation developed near large FeAl3 particles as the main orientation and the cube [{001}〈100〉] orientation originating from the matrix was relatively weak. After annealing at 350 and 500°C, a strong cube texture developed along with a weak {011}〈122〉 orientation. When the cube orientation developed, the copper orientation disappeared most rapidly. These results were discussed based on the interaction between precipitation and recrystallization.
