An effect of the AgCu-alloy sheath on mechanical deformation and superconductivity properties of the Bi2Sr2CaCu2Ox tapes

Journal Article


Abstract


  • Ag-Cu alloy sheathed Bi2Sr2CaCu2Ox superconducting tapes together with Ag-sheathed ones for comparison have been prepared by using powder-in-tube method. Mechanically stronger AgCu alloy improves mechanical and superconducting properties of the tape. Densification of the core by the stronger alloy sheath leads to greater critical current density (Jc). The Jc values of 5·103 A/cm2 and 8·103 A/cm2 were obtained at 77,6 K for 0,2 mm thick Ag- and AgCu-sheathed tapes, respectively. Critical temperature of the AgCu-sheathed tape appeared to be higher than that of the silver sheathed one. The microstructure observation of both kinds of the tapes by means of scanning electron microscopy showed more aligned structure of the Bi-2212 grains and less amount of secondary phases in the Ag-sheathed tape.
