Abstract

The evolution of the grains and voids during the annealing of GdBa₂Cu₃O_7-x is studied. Grain and void area distributions were obtained from four quantitative metallographic determinations made prior to, during and after annealing. The average grain and void diameters grow proportionally to t^{1 2}. The critical grain and void diameters also evolve with the same time dependence. The grain and void growth rates are obtained as a function of the grain and void areas respectively. The voids behave approximately as a second phase in the material, exhibiting a growth process similar to Ostwald "ripening".
