Abstract
1. Способ получения NbSn сверхпроводника, включающий формирование композиционной заготовки сверхпроводника, содержащей единичные волокна из ниобия и из сплава Nb-Ti, которые размещены в матрице из меди или медного сплава, источник олова, диффузионный барьер и медное покрытие, многостадийное волочение и термообработку композиционной заготовки до получения провода нужного поперечного сечения, реакционную термообработку провода для образования сверхпроводящего соединения NbSn, отличающийся тем, что первичную композиционную заготовку единичного волокна формируют из большого количества (более 19) прутков из ниобия и из сплава Nb-Ti, причем количество титана по отношению к ниобию в пересчете на все волокно составляет от 0,5 до 5 масс.%, каждая упомянутая первичная композиционная заготовка единичного волокна выполнена с покрытием из меди или медного сплава.2. Способ получения NbSn сверхпроводника по п. 1, отличающийся тем, что первичная композиционная заготовка единичного волокна содержит также источник олова.1. A method for producing an NbSn superconductor, including the formation of a composite superconductor preform containing single fibers of niobium and an Nb-Ti alloy, which are placed in a matrix of copper or copper alloy, a tin source, a diffusion barrier and a copper coating, multi-stage drawing and heat treatment of the composite preform until a wire of the desired cross-section is obtained, the reaction heat treatment of the wire to form a superconducting compound NbSn, characterized in that the primary composite preform of a single fiber is formed from a large number (more than 19) rods of niobium and Nb-Ti alloy, and the amount of titanium in relation to niobium in terms of the total fiber is from 0.5 to 5 wt.%, each said primary composite preform of a single fiber is made with a coating of copper or copper alloy. 2. The method for producing an NbSn superconductor according to claim 1, characterized in that the primary composite preform of a single fiber also contains a tin source.
