Dew-Hughes, D

An improved method for producing a vanadium-gallium superconductor wire having aluminium as a component is disclosed. The wire is encased in a gallium bearing copper sheath. The superconductors may be fabricated under normal atmospheres and room temperatures by forming a tubular shaped billet having a core composed of an alloy of vanadium and aluminum and an outer sheath composed of an alloy of copper, gallium, and aluminum. Thereafter the entire billet is swage reduced to form a wire and heat treated to form a layer of V/sub 3/Ga in the interior of the wire.
