抄録
Superconducting joints between NbTi and Bi2Sr2Ca2Cu3O10 superconducting wires were successfully fabricated using Bi-added PbSn solders with an in situ sheath-dissolution technique without a removal process for the sheath materials. A backscattered electron image and an energy-dispersive X-ray spectroscopy analysis of the cross-sectional plane of the joints revealed that the joints using Bi-added PbSn solder had a homogeneous morphology with tiny non-superconducting islands. The superconducting joints exhibited high critical currents above 200 A in self-field and 50 A under an applied magnetic field of 5 kOe.
