Improved method of forming superconducting composite article

摘要: A novel process of the production and processing high quality, Tc BSCCO or (Bi, Pb)SCCO superconductors starts with fabrication a forming bundle including plurality billets, each billet containing at least one filament comprising dominant amount tetragonal phase selected intermediate phases, substantially surrounded by constraining metal. The is thermomechanically consolidated to form multifilamentary precursor article applying pressure heat under conditions cooperatively cause interdiffusion said metal interfaces between filaments complete elimination voids in bundle, consolidation step completed before any strain longitudinal deformation performed on bundle. then heated second temperature an inert atmosphere oxygen partial for time period, temperature, period being orthorhombic reacted mixture. It may be deformed elongated desired texture; thereafter third all convert portion final superconducting material.
