Title: Superconducting wire with improved strain characteristics

Abstract

A superconducting wire comprising a superconducting filament and a beryllium strengthened bronze matrix in which the addition of beryllium to the matrix permits a low volume matrix to exhibit reduced elastic deformation after heat treating which increases the compression of the superconducting filament on cooling and thereby improve the strain characteristics of the wire.

  • A superconducting wire is described that is comprised of a superconducting filament and a beryllium strengthened bronze matrix in which the addition of beryllium to the matrix permits a low volume matrix to exhibit reduced elastic deformation after heat treating which increases the compression of the superconducting filament on cooling and thereby improve the strain characteristics of the wire.

  • An object of the invention is the production of superconducting wire or tape with improved strain characteristics. A second object is the production of superconducting wire or tape in which the strain produced by the bending of the wire or the application of a tensile force in normal use increases the effective range of critical current carrying capacity. The addition of an unusually small percentage of beryllium, ranging from 0.01 to 0.1 percent by weight, to a low volume, bronze matrix for a superconducting film adds sufficient tensile strength to the matrix to hold the superconducting filament under higher compressionmore » upon its formation than has been obtained previously with a similarly sized matrix. The higher compression increases the strain limits and provides a more rugged wire with a higher useful current carrying capacity. (TFD)« less
