Abstract

In this study, the $Nb_3Sn$ wire was tried to fabricate by internal tin process to investigate the relationship between the processing parameters in a cold working and the microstructure. The critical current densities of $Nb_3Sn$ wires were evaluated in magnetic fields at 4.2 K. $Nb_3Sn$ compound layer was found to be formed between Nb core and Cu-Sn. The Cu part in the wire transformed to Cu-Sn by the reaction with Sn and the Sn in the Cu-Sn part reacted with Nb.
