Effects of strain and annealing on the intensity and distribution of crystal texture in Cu–12 wt.% Ag

Cu–12 wt.% Ag filamentary composite was prepared by drawing and annealing. The intensity and distribution of crystal texture were determined. The preferred crystal orientation in Ag phase forms more rapidly during drawing strain than in Cu phase. Drawing deformation produces three texture components 〈1 0 0〉, 〈1 1 1〉 and 〈2 1 1〉 in Cu phase and single texture component 〈1 1 1〉 in Ag phase. In a certain strain range, the intensities of all texture components increase with drawing deformation. The 〈1 0 0〉 intensity in Cu phase keeps basically constant and the 〈1 1 1〉 intensity in Cu and Ag phases decreases as the strain exceeds a certain level. Annealing treatment modifies the intensities of deformation texture due to interface migrating, fiber breaking, grain propagating and structure spheroidizing. Annealing at lower temperatures enhances the 〈1 0 0〉 intensity and reduces the 〈1 1 1〉 intensity in Cu phase. Annealing at higher temperatures enhances the 〈1 1 1〉 intensity in Cu and Ag phases.
