· Appl. Phys. Lett.; (United States)
A powder metallurgy based ''liquid-infiltration'' method was used to produce multifilamentary Nb-Sn composite wires. New heat treatments combining relatively low-temperature aging (< or =800 /sup 0/C) and long reaction time (> or = one day) were used to form superconducting A15 Nb/sub 3/Sn. This heat treatment can be used for large conductors and practical magnets. Transmission electron microscopy studies revealed that the A15 Nb/sub 3/Sn was formed in fine filaments which were embedded in the ductile Nb matrix. Small, equiaxed A15 grains extended across the reacted filament. A T/sub c/ onset of 17.9 K with a 0.4-K transition width was obtained. Excellent high-field critical currents, overall J/sub c/'s > or =10/sup 4/ A/cm/sup 2/ in a field of 18 T at 4.2 K, were achieved.
