Fabrication of high-field Nb/sub 3/Sn conductors from Sn-Ta/Nb composites

The mechanism of thick (Nb,Ta)/sub 3/Sn layer synthesis in the Ta-Sn core/Nb (Nb-Ta) sheath composite is studied. The diffusion of Nb from the sheath to the core seems to play a key roll to enhance that of Sn from the core to the sheath synthesizing (Nb,Ta)/sub 3/Sn layer. A simplified powder core p...
