摘要： A method for fabrication of nanometer scale metal fibers, followed by optional further processing into cables, yarns and textiles composed of the primary nanofibers. A multicomponent composite is first formed by drilling a billet of matrix metal, and inserting rods of the metal desired as nanofibers. Hexed or round rods can also be inserted into a matrix metal can. The diameter of this composite is then reduced by mechanical deformation methods. This composite is then cut to shorter lengths and reinserted into another billet of matrix metal, and again the diameter is reduced by mechanical deformation. This process of large scale metal stacking followed by mechanical deformation is repeated until the desired fiber size scale is reached, the fibers being contained in the matrix metal. After size reduction, the composite metal wires may be further processed into built up configurations, depending on intended application, by stranding, cabling, braiding, weaving, knitting, felting, etc., to form yarns or textiles. After the built up configuration is formed, the matrix metal is removed by chemical etching, leaving a cable, yarn or textile composed of the primary nanofibers.

摘要： A superconducting compound of the A-15 crystal structure type is obtained in a composite by a high temperature diffusion between a first metallic component and a second metallic component contained in a bronze alloy. Stability is achieved by including in the composite a quantity of high-conductivity normal material. Diffusion of the second metallic component into the normal material with a resultant degradation of conductivity of the normal material is prevented by placing an impervious barrier layer between the bronze alloy and the normal material. In a specific embodiment, the barrier layer takes the form of an annular shell comprising at least two sectors of dissimilar metals, one of which reacts with a component of the bronze alloy to form a layer of said superconducting compound, and the other of which is substantially non-reactive. Thus, a discontinuous superconducting ring is formed on the barrier layer which prevents flux trapping.

摘要： A method for producing a superconductor having a high copper to superconductor composition (Cu/SC) ratio by cross-sectional area. An assembly is prepared formed of one or more fine filaments of a superconductor composition or of a precursor component for a superconductor alloy composition, which filaments are embedded in a copper-based matrix. The assembly is electroplated with copper to increase the Cu/filament ratio in the resulting product, and thereby increase the said Cu/SC ratio to improve the stability of the final superconductor.

摘要： A composite multifilament superconducting structure is provided, which includes an elongated substrate-carrying, longitudinally-directed, sputtered discrete filament of an A-15 type intermetallic superconductor. In a preferable procedure, a plurality of spaced, generally longitudinal grooves are formed on the surface of an elongated filamentary substrate, preferably a metal wire. The walls of the grooves on the substrate surface are shaped to undercut the curvilinear surface of the substrate located between two adjacent grooves so that at least some of the wall portions of the grooves are geometrically shadowed during the subsequent sputtering step in which a superconductor is sputtered onto the substrate. In particular, a film of a suitable superconducting intermetallic compound having A-15 crystalline structure, such as Nb.sub.3 Ge, is thereupon sputtered onto the grooved substrate and deposits at the bottom of the grooves and at the surface portions of the substrate between grooves. The shadowed wall portions remain substantially deposit-free so that the resultant spaced deposits extend as distinct lines or bands along the substrate to thereby constitute the superconductive filaments. A plurality of such substrates may, if desired, be consolidated into a further composite structure, by bundling the substrates and passing same through a molten metal. The resultant structure may then be sized to yield as a final product a composite of the substrates bearing the superconducting filaments in a surrounding matrix of the metal.

摘要： A method for producing a multifilamentary superconductor containing niobium-tin (Nb.sub.3 Sn). A fully bonded niobium/copper composite billet is formed having a plurality of longitudinally extending channels which are symmetrically distributed with reference to transverse cross-sections of the billet, each channel being filled with an inert removable filler material. The inert filler material is removed to open the longitudinally extending channels in the billet. Tin or a tin alloy is inserted into the channels, and the niobium/copper composite billet with the inserted tin or tin alloy is cold drawn to the desired final dimensions. The drawn composite is then heated to effect in situ formation of the niobium-tin.
