Factors affecting the joining of superconducting BSCCO tapes
Methods of joining BSCCO superconducting tapes were investigated. Monofilament Bi(2223) tapes were fabricated using the powder-in-tube method and groove rolling with critical current in the range of 50 to 70 A. Lap and butt joint configurations were investigated for the green tape. Various thermomec...

| Zusammenfassung: | Methods of joining BSCCO superconducting tapes were investigated. Monofilament Bi(2223) tapes were fabricated using the powder-in-tube method and groove rolling with critical current in the range of 50 to 70 A. Lap and butt joint configurations were investigated for the green tape. Various thermomechanical processes were investigated by changing the pressure, temperature and processing time. Maximum joint efficiencies for butt and lap joints were 35% and 80% respectively. The phase and microstructural development at the joints were investigated using XRD and SEM. |
