Aluminum Oxide Particle Strengthened Niobium-Tin Superconducting Wire

Nano-particle dispersion strengthened copper is co-drawn with Niobium rod to produce DSC-1 Nb wire. Wires of DSC-1 Nb are stacked in a hollow DSC tube and drawn to form a DSC-n.Nb hexagonal wire. A Tin rod is co-deformed with Copper tube to form a Cu-lSn wire. m DSC-n Nb wires and 1 Cu-lSn wires are wrapped by Niobium foil and placed into a Copper tube. This entire assembly is then drawn to a finished size. The drawn composite is subjected to heat treatment with a final stage at 650-700° C. The new wire has higher electric critical current and higher mechanical strength than conventional wires.
