| Popis: |
The shock-modified powder samples described by Morosin et al. (this meeting) have been studied in DTA measurements to 1550°C to determine the influence of shock modification on energy release and on the monoclinic to tetragonal transformation. Energy release over that of control samples is observed to begin at ~ 200°C and continues to the onset of the transformation. The phase transformation temperature is at ~ 1170°C and is unaffected by shock-loading pressure up to 16 GPa. Above that pressure, the transformation temperature is lowered as pressure increases. The decrease in temperature correlates with both the decrease in crystallite size and retention of the tetragonal phase indicated by x-ray diffraction. |
