The effect of precipitation on the evolution of recrystallization textures in an AA 8011 aluminum alloy sheet

The texture of an AA 8011 aluminum alloy sheet cold rolled by 95% showed a typical P-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 degreesC, 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 degreesC, 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.
