Alumina Dispersion-Strengthened Copper Alloy Matrix Ti Added Nb3Sn Wire by the Tube Process
Filamentary superconducting Nb3Sn wire has become increasingly important as a high-field conductor because of its high upper critical field and critical temperature. It has applications in developing high-field and large magnets such as those used in fusion reactors, hybridmagnet systems, and NMR. Compound Nb3Sn, however, suffers from the disadvantage that its superconducting properties rapidly degrade under tensile and bending stress and strain due to reeling and coiling and due to the electromagnetic force generated when a coil is energized, and under thermal contraction stress upon cooling.
