Notes:
Cube textured Ni substrate were fabricated for YBCO coated conductors from the initialspecimens prepared by powder metallurgy (P/M) and casting and the effects of annealingtemperature and reduction ratio on texture formation and microstructural evolutio were evaluated.The initial specimens were rolled by 98.6% and 99.2% reduction ratio and then annealed in thetemperature range of 600℃ to 1200℃. The microstructure and texture were evaluated by opticalmicroscopy and X-ray pole-figure analysis.We observed that microstructure of the initial specimen varied with preparation methods.Textureanalysis indicated that a strong cube texture formed for substrate made by P/M, and the degree oftexture did not significantly vary with annealing temperature of 600℃~1100℃. On the other hand,the texture of substrate made by casting was more dependent on the annealing temperature and twintexture ({221}〈221〉) and several minor texture components started to form at 1000℃. In addition,the texture of substrate made by P/M was significantly dependent on the reduction ratio
