Fabrication of cube textured Ni tapes by in situ thermal and magnetic annealing

Abstract

The development of highly cube textured substrates is important for application of coated high-T-c superconductors. Pure Ni and Ni alloy are the most widely used substrates for coated conductors (CC) because they easily exhibit cube texture through cold rolling and annealing. The textured Ni tape was obtained through recrystallization heat treatment with the line focused infrared heater and the electromagnet. Magnetic field was applied up to 200 G during the heat treatment of Ni tape. Magnetically annealed Ni tape showed stronger cube texture than the samples without magnetic field. full width half maximum (FWHM) value of in-plane texture were 8.3 degrees and 7.8 degrees for the samples annealed without magnetic field and with magnetic field, respectively.
