Abstract :
The critical current of the tapes prepared using continuous processing is significantly enhanced and processing time reduced, compared with that of traditional processing. The effect of conductor pulling speed on the microstructure, phase purity and therefore critical current of the tape is investigated using ESEM, XRD and DC transport measurements.
