Abstract

Superconducting tapes have an inner laminate comprised of a parent-metal layer selected from the group niobium, tantalum, technetium, and vanadium, a superconductive intermetallic compound layer on the parent-metal layer, and a reactive-metal layer that is capable of combining with the parent-metal and forming the superconductive intermetallic compound. A superconducting joint between contiguous tapes comprises, a continuous precipitate of the superconductive intermetallic compound fused to the tapes forming a continuous superconducting path between the tapes.
