High-temperature superconducting tape via the amorphous state

Abstract

A novel approach to preparing ductile high-Tc and high-H c2 superconducting composite tape via the amorphous state is described. This new process, successfully applied to "β-W" Nb3Ge and V3Si, makes full use of the superior mechanical properties characteristic of the amorphous metallic state. Both of these high-Tc materials are difficult to fabricate into tape or wire by conventional techniques.
