Texture evolution and its simulation of cold drawing copper wires produced by continuous casting

Abstract

The texture evolution of cold drawing copper wires produced by continuous casting was measured by X-ray diffractometry and electron back-scatter diffractometry, and was simulated using Taylor model. The results show that in the drawn poly-crystal copper wires produced by traditional continuous casting, 〈111〉 and 〈100〉 duplex fiber texture forms, and with increasing strain, the intensities of 〈111〉 and 〈100〉 increase. In the drawn single-crystal copper wires produced by Ohno continuous casting, 〈100〉 rotates to 〈111〉, and there is inhomogeneous distribution of fiber texture along radial direction of the wires, which is caused by the distribution of shear deformation. Compared with 〈100〉, 〈111〉 fiber texture is more stable in the drawn copper wires. Comparison of the experimental results with the simulated results shows that the simulation by Taylor model can analyze the texture evolution of drawn copper wires.
