| Popis: | Small spherical specimens of ZrO2-1.5mol%Y2O3 with diameters ranging from 150 to 900μm were prepared and the burst temperature was measured on an individual specimen under optical microscope with cooling stage. The range of scatter of the burst temperature increased with decreasing specimen’s size. While the upper limit of the scatter remained nearly the same, the lower limit of the scatter markedly decreased with decreasing specimen’s size. The distribution of potential embryos was deduced by fitting the simulated distribution of burst temperatures to the observed result by adjusting the assumed distribution of potential embryos used for the simulation. |
