Multifilamentary Nb/sub 3/Sn superconductors on the base of high-tin alloyed bronzes for high-field magnets

Multifilamentary Nb/sub 3/Sn superconductors have been fabricated due to the worked out technology of deformed bronze with increased content of tin (16...18 wt%) production. Studies have been made of the effects of bronze composition and thermal treatment conditions on the overall critical current density of multifilamentary Nb/sub 3/Sn superconductors. It is shown, that the use of the bronze with increased content of tin as well as bronze alloying with titanium improves the superconducting properties of composites, especially in high magnetic fields.
