Abstract
Abstract A method of fabricating composite superconductive electrical conductors by disposing at least one rod of flexible substrate material into a billet of an alloy of a normal metal and an alloying metal, co-drawing the billet and rod down to form an elongated conductor and heating the conductor to diffuse the alloying metal into the surface of the flexible substrate, forming a layer of superconductive material in the flexible substrate surrounded by a sheath of normal metal alloy. By this method, composite conductors containing any number of superconductive filaments can be fabricated.
