Title:
Nb-CONTAINING ROD-SHAPED MATERIAL FOR USE IN MANUFACTURE OF SUPERCONDUCTING WIRE AND METHOD FOR MANUFACTURE OF Nb3Sn SUPERCONDUCTING WIRE
Document Type and Number:
WIPO Patent Application WO/2007/060819
Kind Code:
A1
Abstract:
Disclosed is a Nb-containing rod-shaped material which can be used in the manufacture of a Nb3Sn superconducting wire and can impart good processability to Nb or a Nb-based alloy. Also disclosed is a method for manufacture of a superconducting wire having good superconducting properties by using the Nb-containing rod-shaped material. The Nb-containing rod-shaped material can be produced by the steps of: casting a raw material for the rod-shaped material in a mold having a circular or approximately circular cross-section to produce a molded article; and performing a hot working processing or a cold working processing of the molded article into a cylindrical or approximately cylindrical shape using a processing device having a circular or approximately circular cross-section.
