METHOD FOR PRODUCING METAL LAMINATED SUBSTRATE FOR OXIDE SUPERCONDUCTING WIRE, AND OXIDE SUPERCONDUCTING WIRE USING THE SUBSTRATE |
摘要 |
<p>[Problem] A metal laminated substrate for an oxide superconducting wire is provided at a low cost. The metal laminated substrate has high strength, and stable high biaxial orientation in the longitudinal direction. [Means for Resolution] 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 0.2mm 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 50µm 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 10µm is laminated to the metal foil.</p> |
