摘要： Alpha -MoC, having a face-centered-cubic crystal structure, can be prepared in fiber form by subjecting a fiber having a surface comprising dimolybdenum monocarbide to an electric voltage sufficient to raise momentarily the temperature of the fiber surface to a temperature at which the Alpha -MoC is the most stable thermodynamically. The fiber so produced can have a carbon core, or the fiber can be entirely converted to Alpha -MoC. This fiber is useful, for example, as a superconductor material for such applications as windings on magnets. The precursor fiber having a surface comprising dimolybdenum monocarbide can be produced by reacting a carbon fiber with hydrogen and molybdenum pentachloride in a reaction furnace.

摘要： A method for manufacturing a composite wire having an aluminum core and niobium cladding surrounding the core in which a starting structure comprising a rod-shaped aluminum core and a niobium jacket enclosing the core is assembled with a drawing aid surrounding the niobium jacket and then reduced in cross section by repetitive cold-drawing until a solid bond between the niobium and the aluminum is obtained. After removing the drawing aid, the composite structure so formed is then subjected to a surfacesmoothing cold-forming process.

摘要： A multi-filament superconducting composite composed of a plurality of segments that is intrinsically stable. The individual segments are multi-filament composites that have been twisted after assembly and mechanical working and thereafter subsequently deformed. The deformed segments can be triangular or rectangular and are assembled into a second composite. After assembly the second composite is once again twisted. This second twisting transposes the filaments within the segments, thereby producing a superconductor that is resistant to flux jumps induced by self-field losses.

摘要： A plurality of rods are assembled in a predetermined configuration to form a core which is surrounded by a molten matrix metal within a heated crucible. The temperature of the thusly charged crucible''s upper portion is maintained above the matrix metal''s melting point. In this respect, as the heat is applied to the top of the melt, the crucible is maintained in a hot environment while the bottom of the crucible is centrally chilled. In this manner the charge is solidified from the bottom toward the top so that the solidification progresses upwardly and outwardly in a conical pattern. After the controlled solidification is completed the casting is separated from the crucible to form a cored extrusion billet. In one embodiment the rods are separated from the casting and the resulting open holes are filled with superconductive material to form a composite superconductor extrusion billet. In another embodiment the rods themselves are made of a superconductive material so as to eliminate the step of separating the rods from the casting.

摘要： A method of producing tubular conductors includes bending a conductor band to abut the longitudinal edges thereof to form a tube. The conductor band includes a layer of niobium adjacent a layer of an electrically normal conducting metal and ribbon-like niobium chords that define the respective longitudinal edges of the band. After the tube is formed, the niobium chords are joined to each other. The method is especially suited for producing tubular conductors for superconducting cables and the like such as superconducting alternating-current cables.

摘要： A method of fabricating a device, wherein the device comprises a plurality of lengths of material and at least one junction joining two or more of the lengths of material. In a masking phase, a mask is formed on an underlying layer of the device. The mask comprises a plurality of trenches exposing the underlying layer, each trench corresponding to one of the lengths of material. A respective section of two or more of the trenches either (a) narrow down, or (b) are separated by a discontinuity, at a position corresponding to the at least one junction. In a selective area growth phase, material is grown in the set of trenches to form the lengths of material on the underlying layer. The two or more lengths of material are joined at the at least one junction.
