Abstract

The oxide dispersion strengthened copper (ODS-Cu) was composed to Cu stabilizer in Nb₃Sn wires with/without Ta-reinforced filaments to improve the mechanical-electromagnetic property. The wires are 1-mm diameter and heat treated at 650 C for 200 hours. The critical current as a function of the uniaxial tensile strain/stress was explored at 4.2 K, in magnetic fields up to 18 T. The stress/strain sensitivity of the critical current is discussed from a large stress/strain application point of view.
