High current density of NbTi composite

Various NbTi composites that can sustain very high current density are reported. J/sub c/=3000 A/mm/sup 2/ in a 5-T background field has been achieved with 0.85-mm-diameter wire for production and J/sub c/=38000 A/mm/sup 2/ has been achieved in some experimental composites. The development results on a fine filament composite to be used in conjunction with SSC are reported.<
