  • Abstract
    Superconducting Nb3Sn wire was produced by a powder metallurgy method using Nb or Nb-2.9 at.% Ti powder in combination with Sn-x at.% Ga powders (x=3, 4.2, 6.2, and 9.0). Ga additions to the Sn caused considerable solid solution hardening, which improved its workability. It made the Nb-Sn(Ga) powder combination convenient for swaging and extensive wire drawing. Anneals at 950°C produced wires with an overall Jc of 104 A/cm2 at 21.9 T for wires with both Ti in the Nb and 6.2 at.% Ga in the Sn. Comparison of this wire with best Nb(Ti)-Cu-internal Sn(Ti) shows a higher Jc per A15 area, especially in fields of 22 T and above
