Abstract
The relationships between the crystallization mechanism of phases soli difying from the melt, the phase equilibria, the morphology and chemic al composition was investigated in order to establish the influence of the growth rate on the HTC superconductor structure and transport pro perties. Fibers grown with highest pulling rate having higher J(c). Th e J(c) is maximum after annealing at 830 degrees C during 24h. Fibers annealed at 870 degrees C exhibit an onset T-c of 110K.
