Title:
Tiソース・ロッドを用いて(Nb,Ti)3Snワイヤを製造するための方法
Document Type and Number:
Japanese Patent JP2007509466
Kind Code:
A
Abstract:
An improvement is disclosed in the method for producing a multifilament (Nb, Ti)3Sn superconducting wire by the steps of preparing a plurality of Nb or Nb alloy rods where Nb or Nb alloy monofilaments are encased in copper or copper alloy sheaths; packing the Nb or Nb alloy rods within a copper containing matrix to form a packed subelement for the superconducting wire; providing sources of Sn, and sources of Ti within said subelement; assembling the subelements within a further copper containing matrix; and diffusing the Sn and Ti into the Nb or Nb alloy rods to form (Nb, Ti)3Sn. The method is improved by diffusing the Ti into the Nb from a minor number of Ti dopant source rods which are distributed among the Nb or Nb alloy rods.
