Abstract

The impact of oxide dispersion-hardening on its mechanical behavior of powder-in-tube Bi2Sr2CaCu2Ox tapes is investigated. Single-core tapes and multifilamentary tapes with 19 filaments were prepared from commercially available AgMg tubes and powder. The cold-working process was monitored by observing sample microstructures at intermediate stages. The deformation process was optimized to eliminate bridging in the multifilamentary conductor. Short samples were heat-treated and characterized by critical current measurements (Ic) at 4.2 K and 0 T. The maximum filament critical current density (Jc) obtained was 115,000 A/cm2 corresponding to an engineering critical current density (Je) of 22,000 A/cm2.
