Summary

Critical-current density and its temperature dependence in 2 groups of multifilamentary niobium-titanium wires were measured. Further, their pinning behaviour was examined. One group was heat-treated in the fabrication process in order to produce the precipitates of alpha-titanium and the filament diameter of niobium-titanium wires ranges from 0.39 to 1.53 micrometer. The experimental results on this group with copper-copper/nickel mixed matrix or copper-nickel matrix, are given. As the temperature rises, the effect of filament diameter on critical-current density becomes remarkable and the critical-current density-B curves are very different among samples. The pinning properties of these samples are discussed in terms of their upper-critical field and transition temperature.
