摘要： A method for producing electrical super-conductors consisting of a great number of mutually spaced thin filaments of a superconductive material in which diffusion is effected in mutually spaced zones between two adjoining metallic layers, one being vandium and the other a copper-gallium alloy by establishing similar mutually spaced zones in the layers in which the diffusion is either prevented or the superconductive properties of the inter-metallic compound formed by the diffusion is considerably reduced. In one mode of the method, mutuallly spaced zones of non-diffusion in the layers are established by use of mutually spaced zones of molybdenum or tantalum between the layers which prevent interdiffusion therebetween from taking place. In another mode of the method, mutually spaced zones of diminished super-conductive properties are established by use of mutually spaced zones of tin or aluminum which are caused to be diffused into the vanadium layer.

摘要： A method for producing electrical superconductors consisting of a great number parallel spaced thin filaments of a superconductive material in which diffusion is effected in parallel spaced zones between two adjoining metallic layers, one being vanadium and the other a copper-gallium alloy by utilization of a foreign substance between the layers establishing similar parallel spaced zones in which diffusion of gallium into the vanadium is either prevented or the superconductive properties of the inter-metallic compound formed by the diffusion is considerably reduced. The layered material with the foreign substance therebetween is formed into rods the axis of which corresponds to the direction of the parallel spaced zones; these rods are then embedded in a cylinder of a highly electrical conductive matrix material such as copper or aluminum, after which the matrix cylinder is subjected to a drawing operation to effect a reduction in its cross section and hence also the cross sections of the rods embedded therein, and then heat-treated to effect the desired diffusion of gallium from the copper-gallium layers to the adjacent vanadium layers along the parallel spaced zones between zones in which diffusion has been prevented or the superconductive properties of the inter-metallic compound formed at such zones have been reduced by the presence of the foreign substance.
摘要翻译：一种用于制造超导体的方法，其由超导材料的大量平行间隔的细长丝构成，其中扩散在两个邻接的金属层之间的平行隔开的区域中实现，一个是钒，另一个是利用外来的铜 - 镓合金建立类似的平行隔开的层之间的物质，其中镓向钒的扩散被阻止，或通过扩散形成的金属间化合物的超导特性显着降低。其间具有异物的分层材料形成为其轴线对应于平行隔开的区域的方向的杆; 然后将这些棒嵌入诸如铜或铝的高导电性基质材料的圆柱体中，之后对基体圆筒进行拉伸操作以实现其横截面的减小，因此嵌入的棒的横截面然后进行热处理，以使镓从铜 - 镓层到相邻的钒层沿着平行间隔开的区域进行热处理，其中扩散已经被阻止，或者形成在金属间化合物的金属间化合物的超导特性这种区域由于外来物质的存在而减少。

摘要： A PROCESS FOR PRODUCING A SUPERCONDUCTIVE METALLIC CONDUCTOR HAVING A STRIP-SHAPED FORM IN WHICH A PLURALITY OF RODS OF SUPERCONDUCTIVE MATERIAL ARE INTRODUCED INTO BORES IN PRESS BLOCKS MADE OF A STABILIZER MATERIAL. THESE BLOCKS ARE THEN PRESSED OUT INTO CONTINUOUS LENGTHS HAVING A SUBSTANTIALLY RECTANGULAR PROFILE. A FIRST GROUP OF THESE LENGTHS IS THEN DRAWN OR ROLLED TO PROVIDE A FIRST GROUP OF PROFILED WIRES HAVING RIBS ALONG OPPOSITE SIDES, A SECOND GROUP OF THESE LENGTHS IS SIMILARLY WORKED TO PROVIDE A SECOND GROUP OF PLROFILED WIRES HAVING GROOVES ALONG OPPOSITE SIDES, AND THE WIRES OF THE FIRST AND SECOND GROUPS ARE THEN JOINED TOGETHER ALTERNATION AND IN SIDE-BY-SIDE RELATION SUCH THAT THE RIBS AND GROOVES INTERCONNECT. THE JOINED TOGETHER LENGTHS ARE THEN WORKED AGAIN TO ESTABLISH THE FINAL PROFILE OF THE CONDUCTOR.
