The texture of the copper wires were characterized by X-ray diffraction (XRD) and compared with the texture based finite element (FE) simulation predictions. Initial 〈10 0〉 fiber decreases during the drawing process and is replaced by 〈1 1 1〉 fiber. The 〈1 1 1〉 oriented grains are predominant in a single step drawing compared to a multiple step of the equivalent area reduction. The finite element analysis takes into account active crystallographic slip and orientation effects during the drawing process. Regions at the interface of die–wire exhibited complex textures, which was widely seen in the multiple step drawing pattern.||URI:||https://hdl.handle.net/10356/99112
