Solid solutions of Niobium-tin for preparing Nb3Sn superconductors

Solid solution alloys of niobium with concentrations of Sn from 1 to 9 wt% have been prepared by quenching the solid solution from about 2100°C to room temperautre. These materials are relatively ductile and can be deformed, by swaging, into the desired shape, after which the material is reacted at about 800°c. The resulting structure is a mixture of Nb3Sn and Nb, with as much as 45% of the volume containing Nb3Sn.
