Effect of Solidification Conditions on Partial Melt Processed Bi2212/Ag Round Wire

This is the authors' abstract. We don't add key points for this paper.

In this study, we report the effect of cooling from the peak temperature reached during partial melt processing on the critical current for a Bi2212/Ag wire. A single-stage cooling approach is compared to two-stage cooling. For two-stage cooling, the first stage cooling rate and the cooling rate transition temperature were varied to investigate the effects of undercooling on the solidification behavior of the 2212 phase. Two-stage cooling results in higher Iccompared to single-stage cooling, and the cooling rate transition temperature was found to have a greater effect on Icthan the initial cooling rate.
