Mechanical and Superconducting Properties of NbTi Reinforced MgB₂ Wires

Article Preview

Abstract:

The strengthening abilities of NbTi for 6-filamentary MgB_1.9(TiC)_0.08/Nb/Cu wires and the electrical properties have been investigated. The NbTi reinforcing core was suitable for manufacturing MgB₂ wires. It was observed that with the sintering temperature increasing, the yield strength decreased. The plasticity improved while the strength changed little by introduction of intermediate annealing during the cold processing of the wires. The transport properties of the wire degraded to some degree due to intermediate annealing. The mechanical properties have already met the application requirements of superconducting magnets in low field with the critical engineering current I_c above 90 A (J_ce exceeding 7.9×10³ A/cm²) at 35 K in self-field.
