  • Abstract
    A rapid solid-liquid reaction mechanism has been used to form A15 Nb3Sn in the liquid-infiltration processed Nb-Sn wire. Small, equiaxed A15 grains across the fine reacted filaments of 0.2-1.0 μm thickness were revealed with the transmission electron microscopy studies. A uniform Sn concentration near the stoichiometry was found in the A15 region. High inductive Tc´s of 17.9K with sharp transition widths (<0.3K) and excellent overall Jc´s of 104A/cm2at 19T and 4.2K were achieved. Mechanical properties of the reacted wire are no worse than those of typical commercial bronze-process Nb3Sn conductors, and εirrevis slightly higher.
