摘要： A cabled conductor is provided for use in a cryogenically cooled circuit including refrigeration having a predetermined operating temperature and efficiency. The conductor includes multiple conductor strands cabled about the longitudinal axis of the conductor at a preselected cabling period, each strand including a composite of superconducting ceramic in intimate contact with conductive matrix material. Each filament has high performance regions in which the filament material is well-textured with its preferred direction aligned perpendicular to the widest longitudinal cross-section of the conductor alternating with poorly superconducting regions which are at least about half the diameter of a filament in length and in which the superconducting ceramic filament is strained by transposition in excess of its critical strain limit. In the poorly superconducting regions, the conductive matrix material provides an alternate current path. The ratio of the average length of the poorly superconducting regions to the preselected cabling period is less than about (&rgr;300e/&rgr;oe)&egr;E, where &rgr;oe is the resistivity of the composite at the operating temperature; &rgr;300e is the resistivity of the composite at 300 Kelvins; and &egr; is the predetermined efficiency of the refrigeration means at its operating temperature. In the preferred embodiment, this ratio is less than 1:4, and preferably less than 1:20.

摘要： A cabled conductor comprises a plurality of transposed strands each comprising one or more preferably twisted filaments preferably surrounded or supported by a matrix material and comprising textured anisotropic superconducting compounds which have crystallographic grain alignment that is substantially unidirectional and independent of the rotational orientation of the strands and filaments in the cabled conductor. The cabled conductor is made by forming a plurality of suitable composite strands, forming a cabled intermediate from the strands by transposing them about the longitudinal axis of the conductor at a preselected strand lay pitch, and, texturing the strands in one or more steps including at least one step involving application of a texturing process with a primary component directed orthogonal to the widest longitudinal cross-section of the cabled intermediate, at least one such orthogonal texturing step occurring subsequent to said strand transposition step. In a preferred embodiment, the filament cross-section, filament twist pitch, and strand lay pitch are cooperatively selected to provide a filament transposition area which is always at least ten times the preferred direction area of a typical grain of the desired anisotropic superconducting compound. For materials requiring biaxial texture, the texturing step preferably includes application of a texturing process with a second primary component in a predetermined direction in the plane of the widest longitudinal cross-section of the conductor.

摘要： A method of forming a textured superconductor wire includes constraining an elongated superconductor precursor between two constraining elongated members placed in contact therewith on opposite sides of the superconductor precursor, and passing the superconductor precursor with the two constraining members through flat rolls to form the textured superconductor wire. The method includes selecting desired cross-sectional shape and size constraining members to control the width of the formed superconductor wire. A textured superconductor wire formed by the method of the invention has regular-shaped, curved sides and is free of flashing. A rolling assembly for single-pass rolling of the elongated precursor superconductor includes two rolls, two constraining members, and a fixture for feeding the precursor superconductor and the constraining members between the rolls. In alternate embodiments of the invention, the rolls can have machined regions which will contact only the elongated constraining members and affect the lateral deformation and movement of those members during the rolling process.

摘要： Disclosed Is a process for the fabrication of rare earth or rare earth alloy materials in the form of fine wires for refrigeration regenerator applications. The wire is a composite consisting of a metal core and a metal sheath. The core material is comprises of at least a 20 atomic percent portion of rare earth metal as a pure metal, an alloy with other rare earth metals, or an intermetallic compound alloy with one or more non rare earth metals. The sheath material is essentially immiscible with the rare earth in the core, has no magnetic phase transitions in the temperature range for the intended operation, and has good corrosion and oxidation resistance. The sheath material is typically a small portion of the total composite wire cross section. The composite wire is fabricated from the co-reduction of an assembled billet by conventional wire processing techniques.
