Reinforced high temperature superconducting silver wire

摘要

Reinforced high temperature superconducting silver wire and materials, and methods of producing reinforced high temperature superconducting silver composite wire. More specifically reinforcement materials and assemblies for attaining much higher stress, bend and surface indent tolerances at practical conductor dimensions are described. The reinforced wire or methods can include a silver wire core and a layer of high strength reinforcing metal.

1. A reinforced high temperature superconducting composite wire comprising:
a silver/superconducting oxide composite wire core of substantially round cross section having a length and an exterior surface; one or more split cylinder shaped layers of high strength reinforcing metal circumferentially surrounding a substantial portion of the exterior surface of the silver wire core at a point along the length of the composite wire; and a bonding material between the silver wire core and the reinforcing metal; and the reinforcing metal and the bonding material at the point along the length of the composite wire occupy less than about 50 percent of the total composite wire cross sectional area and the tensile stress tolerance of the composite wire exceeds about 300 Megapascal, and tensile strain tolerance exceeds 0.30 percent when the composite wire is below a temperature of about 300 Kelvin.
