NbTi SUPERCONDUCTING WIRE ROD |
摘要 |
The present invention relates to a NbTi superconducting wire which contains a Cu matrix and a plurality of NbTi alloy filaments disposed in the Cu matrix, the NbTi superconducting wire having a substantially circular cross-section perpendicular to an axis thereof, in which a ratio of the cross-section area of the Cu matrix to the total cross-section area of the NbTi alloy filaments (cross-section area of Cu matrix/total cross-section area of NbTi alloy filaments) is equal to or greater than 5.0 and smaller than 15.0, the NbTi alloy filaments have an average diameter d of 30 to 200 µm, and the ratio (S/d) of an average interval S between the NbTi alloy filaments to the average diameter d of the NbTi alloy filaments is in the range of 0.10 to 0.40. The NbTi superconducting wire of the invention exhibits high filament uniformity (n value) and has a high electrical field current density Jc even with a high copper ratio. |
