Abstract :
The effects of the variation of microstructures in NbTi superconducting wires on the superconducting properties are investigated. The microstructures of specimens having a high J c were investigated. The relationship between critical current density and the final drawing strain is simulated based on the observation of microstructures, and good agreement with the experimental results is obtained. Results indicate that Jc tends to increase with increases in volume fraction
