Abstract:

Biaxially cube textured polycrystalline Cu200 substrate tapes were produced for high temperature superconducting HTS coated conductor applications. A comparison is made between Cu substrates fabricated by reverse cold rolling followed by recrystallization, from stock materials that were obtained in the form of extruded rod and rolled plate. Detailed x-ray diffraction XRD studies and orientation imaging microscopy OIM were performed to measure the in-plane alignment, out-of-plane alignment, and microtexture at various deformation levels and annealing temperatures. The rod starting geometry proved to have superior biaxial alignment with a predominant 220 deformation texture after rolling.
