METHOD FOR THE MANUFACTURE OF A SUPERCONDUCTOR HAVING AN INTERMETALLIC TWO ELEMENT COMPOUND

摘要

A method of manufacturing a superconductor having a superconductive intermetallic compound made of two elements and having an A-15 crystal structure in which at least one core consisting of a ductile element of the compound is surrounded with a jacket of an alloy containing a ductile carrier metal and the second element of the compound after which the jacket is then covered with a tantalum layer and that layer then covered with a sheath of metal which is electrically and thermally highly conductive and is electrically normally conducting at the operating temperature of the superconductor. The structure thus obtained is then subjected to a cross section-reducing deformation after which it is heat-treated to form the intermetallic compound.
