Phase Stability and Residual Stress Field in Nano-Structured 3Y-TZP
Phase stability of 3Y-TZP was evaluated by acceleration test in water vapor environment and Raman spectroscopy. We found that the phase stability was affected not only by grain size but also by residual stress field, which could be quantitatively measured by Raman piezo-spectroscopy and controlled by sintering temperature. This study shows that Raman spectroscopy is a very useful technique for non-destructive analysis of 3Y-TZP.
