Abstract
- A study was conducted on the temperature and field dependences of critical current in direct-heated Nb-tube processed Nb3Al wires. The 0.74 mmphi Nb3Al wires include 121x121 7-core elementary Nb/Al-Mg composites. Results reveal that the volume pinning force of the wires was in agreement with Kramer's scaling law for the measured temperature range 4.2-16 K. Grain boundaries were found to be the most probable pinning source since the phase grains formed were fine.
