Evolution of Drawing Texture for A6 Aluminum Conductor

Evolution of drawing texture for A6 aluminum conductor with the drawing process was investigated by macro and micro-texture analysis. The results show that the fiber-like deformation texture of 111 and 100 formed in the drawing process, and 100 texture reduced while 111 texture enhanced with the increasing strain. The distribution of deformed texture was of homogeneity along the radial direction of wire: the deform texture transformed from strong 100 texture(~52% volume fraction) in the surface to strong 111 texture(~55%) in the center by moderate strains; the radial gradient texture was weakened and a strong 111 texture(70%) formed in the overall wire by high strains. Moreover,the core hardness of the wire was higher than that of the surface, which attributed to the texture gradient distribution along the radial. Adjusting the drawing process to optimize the dislocation density and texture as well as their distribution in the wire is an effective route to improve the strength and conductive properties of the A6 aluminum conductor.
