Properties of Ti alloyed multifilamentary Nb/sub 3/Sn wires by internal tin process

OSTI ID:6485093

Influence of Ti addition to the Sn core on the critical current density J /SUB c/ of multifilamentary Nb/sub 3/Sn wires fabricated by the internal tin process was studied. The addition ( about1.5 wt% Ti) improved the values of J /SUB c/ at very high magnetic fields over those for the pure Nb/sub 3/Sn, e.g., J /SUB c/ about140 A/mm/sup 2/ at 18 T. This is 3-4 times greater than a similarly processed pure Nb/sub 3/Sn wire and is within about10% of the highest critical current density measured for the Ti alloyed bronze processed Nb/sub 3/Sn wires.
