摘要

Bi-2223/Ag multifilamentary tapes were fabricated using a hot-pressing technique to investigate its effect on grain connectivity and flux pinning. The critical current density in tapes after hot-pressing was doubled. J/sub c/ increased from 26000A/cm/sup 2/ to 56100A/cm/sup 2/ in a 19-filament tape. However, the critical current density in an applied magnetic field was not improved by hot-pressing. The fraction of strong links (I/sub C0//sup s//I/sub C0/) was improved from 47% to 68% in a 19-filament tape due to hot pressing. Microstructural analysis showed that hot-pressing improved grain connectivity, increased core density and reduced secondary phases.
