Abstract:
A method of joining tape-shaped superconducting wires, said method comprising:a step of preparing tape-shaped superconducting wires formed of metal-coated oxide superconductors having portions to be joined;a step of separating metal coatings from first sides of said portions to be joined for exposing said oxide superconductors of said tape-shaped superconducting wires;a step of overlapping exposed said oxide superconductors with each other so that said exposed oxide superconductors directly contact each other; anda step of joining overlapped said oxide superconductors to each other,wherein the overlapped superconductors are joined together by deformation processing and heat treatment to achieve a joined member having a thickness smaller than the sum of those of the superconducting wires to be joined and being capable of generating superconducting state at liquid nitrogen temperature.
