Effect of ECAP on Change in Microstructure and Critical Current Density of Low Temperature Super-Conducting Monowire

The critical current density (Jc), which is a major performance parameter of low temperature superconducting Nb-46.5 wt%Ti wire, can be improved by uniformly dispersed fine α-Ti precipitates since they serve as a flux pinning center. The high volume fraction of α-Ti precipitates at grain boundary in...
