摘要： A Nb3Al superconducting wire and method for fabricating the same wherein Nb and Al powders in combination, or Nb-Al alloy powders are encapsulated in a metal tube, preferably copper or copper-alloy (e.g., CuNi), and the resultant composite is processed by conventional means to fine wire. Multifilamentary composites are produced by rebundling of the powder-filled wires into metal tubes followed by conventional processing to wire of a desired size. It is required for the use of Nb and Al powders in combination that the Nb and Al powder particle size be less than 100 nm. In the use of Nb-Al alloy powders, it is preferred, but not required, that the powder particle size be similarly of a nanometer scale. The use of nanometer-scale powders is beneficial to wire fabrication, allowing the production of long wire piece-lengths. At final wire size, the wires produced by practice of the present invention are heat treated at temperatures below the melting point of copper (1083°C), with the heat treatment causing conversion of the powder cores or filaments to the A15 superconductor Nb3Al. The resulting superconducting wires display critical superconducting properties previously achievable only by methods employing temperatures well in excess of the melting point of copper.
摘要翻译：一种Nb3Al超导线及其制造方法，其中组合的Nb和Al粉末或Nb-Al合金粉末封装在金属管中，优选铜或铜合金（例如CuNi）中，并且所得复合材料由常规手段细线。通过将粉末填充的线重新连接到金属管中，然后通过常规加工成所需尺寸的导线来生产多丝复合材料。需要组合使用Nb和Al粉末，Nb和Al粉末粒度小于100nm。在使用Nb-Al合金粉末时，优选但不是要求粉末粒径类似于纳米级。使用纳米级粉末有利于电线制造，允许生产长的电线片长度。在最终丝尺寸下，通过实施本发明生产的丝线在低于铜熔点（1083℃）的温度下进行热处理，热处理引起粉末芯或细丝转化为A15超导体Nb3Al。所得到的超导线材显示出仅通过使用超过铜熔点的温度的方法才能达到的临界超导特性。

摘要： A method for producing a superconductor by partial inter diffusion of layers of metal under a diffusion heat treatment to provide a ductile beta phase alloy, along with undiffused metal layers to permit ease of extrusion and drawing to fine layer thickness. At some point in the reduction the layers are further diffused to give an alloy superconducting product which is optimal for the high field (5-9T) of interest in contact with a non-superconducting layer. This optimal diffusion is preferably accomplished after a sufficient reduction such that the individual metal layers are 2.5 - 15 microns thick.
摘要翻译：一种通过在扩散热处理下金属层的部分相互扩散来制造超导体的方法，以提供延性β相合金以及未扩散的金属层，以允许易于挤出和拉伸成细的层厚度。在还原的某一点上，层进一步扩散以产生对于与非超导层接触的感兴趣的高场（5-9T）最佳的合金超导产品。这种最佳扩散优选在充分还原后实现，使得各个金属层的厚度为2.5-15微米。

摘要： A method for making superconducting material useful for forming electrolytic devices comprising the steps of establishing multiple valve metal rods in a primary billet of a ductile material; working the primary billet to a series of reduction steps to form said valve metal rods into a plurality of elongated elements surrounded at least in part by the ductile material; cutting the elongated elements from step (b) and bundling the cut elements to form a secondary billet; working the secondary billet through a series of reduction steps followed by rolling to final thickness; removing the ductile material, whereby to leave valve metal elongated fibers; and sintering the elongated fibers from step (e) under vacuum.

摘要： A process for forming a porous electrolytic compact by establishing multiple valve metal components in a billet (20) of a ductile metal. The composite billet is worked through a series of diameter reduction steps (22, 24, 30), to form the components into elongated elements, each element having a thickness less than 5 microns. The last diameter reduction step (32) is accomplished with the elements being surrounded by a confining layer of valve metal.
