Abstract
Critical current, magneto-optical (MO) images and ac susceptibility of Ag/BSCCO-2223 tapes were studied at various stages of tape processing. It was found that long-range connectivity of the tape core destroyed by intermediate deformation was restored in less than lh of subsequent sintering. Transverse flux penetration observed in MO images of sintered tapes are supposedly weak link channels remaining at locations of unhealed or only partially healed deformation-induced cracks.
