The evaluation of current transfer effects in normal metal/superconductor interfaces are used in the design of splices and joints of superconducting coils. We evaluated the low electric resistance by applying transport currents up to 100 A and under self magnetic fields using the resistive four prob

Tensile test was carried out for Bi2223/Ag/Ag alloy composite tapes at RT, 77 and 7 K. Two yielding points are observed in the stress-strain curves. From the stress-strain behavior of the components and critical current (I c ) as a function of tensile strain, it was found that the microscopic reason
It was attempted to estimate the distribution of irreversible bending strain for critical current of the Bi2223 composite tape. In the modeling, the shape of the core composed of the current transporting Bi2223 filaments and Ag, and the damage strain parameter given by the difference between the int
The strain dependence of the critical current, I c , of Bi2223/Ag/Ag-alloy composite superconducting tapes has been studied both experimentally and analytically under bending deformation. The microscopic observation after bending deformation indicated that delamination existed inside Bi2223 filament
