Abstract

New Nb-rod-processed CuNb reinforced Nb₃Sn superconducting wires have been developed for large high field magnet applications. The critical current, I_c, mechanical properties and resistivity are investigated. The residual strain and irreversible strain are found to be 0.35% and 0.77%, respectively. We found that the Nb-rod-processed wire has a large strain sensitivity to I_c. However, the wire has good mechanical properties, having a 0.2% proof stress of 280 MPa and a Young's modulus of 150 GPa. This means that the stress sensitivity of the I_c for the wire is small. These results show that the Nb-rod-processed wire is suitable as a strand of Rutherford cable for a high field superconducting magnet.
