Void and Phase Evolution during the Processing of Bi-2212 Superconducting Wires monitored by combined fast Synchrotron Micro-tomography and X-Ray Diffraction
Recent study of the current-limiting mechanisms in Bi-2212 round wires has suggested that agglomeration of the residual Bi-2212 powder porosity into bubbles of filament-diameter size occurs on melting the Bi-2212 filaments. These pores introduce a major obstacle to current flow, which greatly reduce...
