Abstract
Ag (silver) can be used for YBa$_2$Cu$_3$O$\_$7-$\delta$/(YBCO) coated conductor tape as the substrate on which YBCO can be deposited directly because of the chemical compatibility of Ag with YBCO. We have fabricated rolled Ag tapes with various total reduction ratios and different thicknesses. As-rolled Ag tape was recrystallized at 750$^{\circ}C$ for 30min in air and vacuum of 10$\^$-3/ torr. The orientation distribution functions (ODF) calculated from three x-ray pole figures of as-rolled and recrystallized tapes were analysed. As the total reduction ratio increased from 94 to 98%, the development of {110}texture of as-rolled Ag improved. Under the present experimental condition, maximum {110}ODF value of Ag tape was obtained for the sample with 94% total reduction ratio which was recrystallized at 750$^{\circ}C$ for 30min in vacuum of 10$\^$-3/ torr.
