Method for producing metal laminated substrate for oxide superconducting wire, and oxide superconducting wire using the substrate
Abstract:
A metal laminated substrate for an oxide superconducting wire is manufactured such that a non-magnetic metal plate T1 having a thickness of not more than 0.2 mm and a metal foil T2 made of Cu alloy which is formed by cold rolling at a draft of not less than 90% and has a thickness of not more than 50 μm is laminated to each other by room-temperature surface active bonding, after lamination, crystal of the metal foil is oriented by heat treatment at a temperature of not less than 150° C. and not more than 1000° C. and, thereafter, an epitaxial growth film T3 made of Ni or an Ni alloy having a thickness of not more than 10 μm is laminated to the metal foil.
