摘要： A superconductor which is superconducting of a predetermined high field and low temperature is formed by combining a plurality of metal bodies to form a composite structure. The metal bodies are selected from transition metals such as niobium, tantalum, zirconium, hafnium and vanadium, and alloys of such metals, alternate bodies being formed of ductile alloys of the metals which are not superconducting at the predetermined high field. The alternate bodies of transition metals are reacted to form a ductile superconducting ternary alloy zone at the interfaces of these bodies. The extent of the reaction is limited so as to maintain areas of transition metal and transition metal alloys which are not superconducting at the high field. The composite structure is reduced sufficiently that each non superconducting zone is less than 1000A.degree. thick and serves as an artificial pinning site for each adjacent superconducting zone.

摘要： A superconductor manufacturing process provides electrical insulation and enhanced transverse electrical resistivity of multifilament superconductor strands based on Nb.sub.3 Sn. The process includes forming, during the early manufacturing steps in which the product is relatively short and of large cross section, resistive barriers around bundles of filaments in an oxide powder doped with conductive materials. In subsequent steps, an electrically insulative powder is used to insulate between a copper tube surrounding the bundles of filaments and an outer resistive ring or to insulate around multifilament strands.

摘要： A superconducting member is manufactured by mechanical fabrication to final dimensions of a matrix comprising a base material, such as niobium, an alloy essentially consisting of a carrier material and at least one element, such as tin, a metal for stabilization and a barrier material protecting the metal for stabilization. After mechanical fabrication a superconducting compound of the base material and the element is formed by heat treatment to cause a solid state reaction. The barrier material prevents diffusion of any of the components into the metal for stabilization.

摘要： A method of manufacturing a superconductor having a superconductive intermetallic compound made of two elements and having an A-15 crystal structure in which at least one core consisting of a ductile element of the compound is surrounded with a jacket of an alloy containing a ductile carrier metal and the second element of the compound after which the jacket is then covered with a tantalum layer and that layer then covered with a sheath of metal which is electrically and thermally highly conductive and is electrically normally conducting at the operating temperature of the superconductor. The structure thus obtained is then subjected to a cross section-reducing deformation after which it is heat-treated to form the intermetallic compound.
