    • A superconductive article is made by inserting a rigid mandrel into an internal cavity of a first metallic tube, said tube having an interior surface and an exterior surface, said interior surface defining the interior cavity, forming a layer of a superconductive material or superconductive precursor upon the exterior surface of said first metallic tube, machining the layer of superconductive material or superconductive precursor to a predetermined diameter to form an intermediate article configured for insertion into a second metallic tube having an interior diameter corresponding to the predetermined diameter, inserting the machined intermediate article into a second metallic tube having an internal diameter corresponding to the predetermined diameter of the intermediate article to form a composite intermediate article, reducing or ironing the composite intermediate article to a predetermined cross-sectional diameter, and sintering the reduced or ironed composite intermediate article at temperatures and for time sufficient for the superconductive material or superconductive precursor to exhibit superconductivity.
    • 通过将刚性心轴插入第一金属管的内腔中而形成超导制品,所述管具有内表面和外表面,所述内表面限定内腔,形成超导材料层或超导前体层 所述第一金属管的外表面将超导材料层或超导前体层加工成预定直径以形成中间制品,所述中间制品构造成用于插入到具有对应于预定直径的内径的第二金属管中,将加工的中间体 进入具有对应于中间制品的预定直径的内径的第二金属管,以形成复合中间制品,将复合中间制品还原或熨烫至预定的横截面直径,并将还原或熨烫的复合中间体 在超导材料或超导前体的温度和时间足以表现出超导性。
