Title:
特に内部酸化用の、Ｎｂ３Ｓｎ含有超伝導ワイヤを製造するためのモノフィラメント
Document Type and Number:
Japanese Patent JP6910406
Kind Code:
B2
Abstract:
A monofilament (100) for producing an Nb3 Sn-containing superconductor wire (33) includes a powder core (1) with an Sn-containing powder, a reaction tube (3) composed of an Nb alloy that includes Nb and at least one further alloy component X. The powder core is disposed within the reaction tube. The monofilament also includes at least two sources (4) for at least one partner component Pk. A respective source includes one or more source structures at a unitary radial position in the monofilament. The source structures are at different radial positions. The alloy component X and the partner component Pk form precipitates XPk on reaction annealing of the monofilament in which Sn from the powder core and Nb from the reaction tube react to produce Nb3 Sn. The powder core is disposed in a moderation tube, which is disposed within the reaction tube. This provides a monofilament with improved current carrying capacity.
