Deformation and annealing textures of drawn aluminum bronze wires
Axisymmetrically drawn products of fcc metals with medium and high stacking fault energies have fiber textures consisting of major <111> component and minor <100> component, which are known to change to the <100> orientation after recrystallization and again to the <111> orientation after further annealing often at higher temperatures. In this study, Cu-7.3% Al alloy with a very low stacking fault energy was drawn by 10 to 70% in area reduction. The orientation density ratio of the <100> component to the <111> component in the drawn wire decreased with increasing reduction up to 50% and then increased with further increasing reduction. As the <111> component decreased, its twin component, the <115> orientation, increased. When the 70% drawn wire, whose texture consisted of strong <111> component and weak <115> and <100> components, was annealed at 500, 600, and 700degreesC, the <111> component dominated the annealing texture The results were discussed in term of recystallization and grain growth.
