Effect of stacking fault energy on evolution of recrystallization textures in drawn wires and rolled sheets
The drawing textures of aluminum, copper, gold, silver, and Cu-7.3% Al bronze wires are approximated by major < 111 >+minor < 100 >, except silver wire, which can have the < 100 > texture at extremely high reductions. The < 111 > component in the drawing textures of aluminum, copper, gold, and silver transform to the < 100 > component after recrystallization. On the other hand, the < 111 > deformation texture of the Cu-7.3% Al bronze wire, which has very low stacking-fault-energy, remains unchanged after recrystallization. The Brass component {110}< 112 > in rolling textures of high stacking-fault-energy metals such as aluminum and copper alloys changes to the Goss orientation {110}< 001 > after recrystallization. However, the Brass orientation in rolling textures of low stacking-fault-energy fcc metals such as brass appears to change to the {236}< 385 > orientation after recrystallization. These results seem to be related to the stability of dislocations during annealing.
