61-Filaments Bi-2223/Ag superconducting tapes have been joined by diffusion bonding. The critical currents (I C s) of the joints are obtained by using standard four probe method under no magnetic field in the liquid nitrogen. The microstructures of the joints are evaluated by the electron microscope
Soldered joints of Bi-2223/Ag-sheathed high temperature superconducting multifilamentary tapes were fabricated using 63 wt.%Sn-34 wt.%Pb-1 wt.%Bi-2 wt.%Ag paste. The soldered joints were observed by scanning electron microscope (SEM) and X-ray diffraction (XRD). Moreover, the electrical properties o
The effect of sweep rate of applied current (dI/dt) on critical current (I c ) of Ag-sheathed Bi 2 Pb x Sr 2-x Ca 2 Cu 3 O y (Ag-Bi-2223) tapes was studied by the four-probe measurement method of V-I curves. It was found that the V-I curves were affected apparently by dI/dt, resulting I c , decrease
