ABSTRACT:
Superconductor wire, and methods of constructing same, including one or more filaments formed of submicron-particle superconductor powder each surrounded by an encapsulating sheath having a composite wall. The composite wall includes a ductile outer skin surrounding a relatively harder, higher yield strength inner wall portion. The harder, higher strength inner wall portion improves dimensional uniformity of the filaments as the wire is fabricated, with the potential for enhanced superconducting performance, while the ductile outer skin enhances metallurgical bonding between the outer skins of adjacent filaments, to ensure a homogenous, thermally conductive and normally electrically conductive matrix.
