Abstract

The microstructures and the solidification behavior in unidirectionally solidified Y–Ba–Cu–O/Ag (YBCO/Ag) superconducting current leads were investigated. The solidification model of this system was discussed by the Y2Ba1Cu1O5–Ba3Cu5Ox–Ag quasiternary phase diagrams constructed by analysis of the solute compositions in the melt. The diffusion fields and the spacing between silver particles in the YBCO/Ag system were discussed. The relationship between the shapes of entrapped silver particulates, the miscibility gap in the phase diagram, and the wetting behavior at the growth interface in two-dimensional monotectic reactions were also discussed.
