摘要:Abstract(#br)Cube-textured Ag tapes of Ag{1 0 0} 〈0 0 1〉 were investigated to obtain in-plane aligned Re123 films, where Re represents Y, Gd, Sm and Nd by a continuous chemical vapor deposition technique. Y123 and Gd123 films formed on Ag{1 0 0} 〈0 0 1〉 tapes showed two...

摘要:Abstract(#br)In case of the cube textured (CUTE) Ag substrate, recrystallization process of as-rolled Ag substrate in various atmosphere changed surface flatness of the substrate. When the substrate was heated in a vacuum chamber with a oxygen partial pressure of less than 1...

摘要:Abstract(#br)Silver sheathed Bi-2212 multifilamentary tapes with 19–55 cores were successfully developed through the continuous pressing followed by a partial melting process. The multifilamentary tapes showed J c 's of 1800 A/mm 2 ( B tape face) and 1100 A/mm 2 ( B ⊥tape) a...
