ABSTRACT:
A multifilamentary, copper or copper alloy clad superconductive wire, comprising a superconductive, intermetallic compound Nb.sub.3 Sn or V.sub.3 Ga, having an A-15 crystal structure, and at least one additive metal from the group consisting of rare earth elements of atomic number 57 to 71, Th, U, Ti, Zr, Hf, V, Nb, Ta, Mo, Fe, Co, Ni, Pd, Cu, Ag, Al, and Pt. The additive is present in the wire within the A-15 phase in the form of uniformly and finely distributed, at least partially undissolved axially parallel inclusions at grain boundaries of the crystals and/or at an interface between the A-15 phase and the copper or copper alloy, or at an interface between the A-15 phase and a separate phase.
