• 論文の詳細を見る

• We have prepared Y-Ba-Cu oxide superconducting wires with stainless-steel, Cu-Ni alloy or silver sheath by a powder metallurgy technique, and confirmed superconductivity in stainless-steel or silver-sheathed wires. During the hea-treat-ment, a dielectric layer was formed at the interface between the sheath and Y-Ba-Cu oxide in stainless-steel-sheathed and Cu-Ni alloy-sheathed wires. The diffusion of the sheath element into Y-Ba-Cu oxide was analyzed using EPMA. The highest critical current dernsity, 560 A/cm^2, was obtained for a silver-sheathed wire which was heat-treated in oxygen flow. A multicored wire was produced.
