The cube textured pure Ni and non-magnetic Cu-Ni tapes were obtained by rolling and recrystallization, and these tapes are suitable as substrates of the second generation high temperature superconducting tape. The texture of tapes was studied using Orientation Distribution Function (ODF) and φ-scans. The results indicate that sharp cube texture of Cu0.70Ni0.30 and pure Ni was formed at 1000 ℃ and that of Cu0.85Ni0.15 was formed at 900 ℃. The intensities of cube texture differ from each other. Uniform equiaxial crystallites are formed in all the tapes and the size of Cu0.85Ni0.15 is larger than that of Cu0.70Ni0.30 and pure Ni. Annealing twin is formed in Cu0.85Ni0.15 and Cu0.70Ni0.30.
