Long length {110}<110> textured Ag tapes for biaxially oriented YBa/sub 2/Cu/sub 3/O/sub 7/ coated conductors

A good {110}<110> texture was successfully obtained by the only 3 minutes post-roll annealing by the careful control of the cold-roll process. Such a short annealing time will enable to skip the final annealing process of the Ag tape for the recrystallization and to save the cost of the furnace, energy and the time. We could obtain 20 m long cold-rolled Ag tape with enough uniformity, which can be converted to the {110}<110> textured Ag tape by the only short time annealing. The 3 cm samples, cut from both end and from the middle part of the 20 m long cold-rolled tape and then annealed at 800 (degree)C for 5 minutes, were confirmed to have smooth surfaces and the shallow grooves at grain boundaries, as well as good {110} <110> textures from the X-ray {100} pole figures and the SEM photographs.
