Paper Title:
Stress Relaxation on Polished Cross-Sections of Al2O3/ZrO2 FGM Discs Measured by Raman Spectroscopy
  Abstract

The residual stresses were measured on polished cross-sectioned Al2O3/ZrO2 FGM discs by means of Raman spectroscopy. The experiments revealed that it is possible to measure the residual stresses caused by the thermal expansion mismatch between the alumina and zirconia phase as a function of the position in the FGM. These experimental data are in excellent agreement with the thermal stresses calculated from the local composition using the model of Taya. However, the stresses due to the generated FGM profile could not be measured by means of Raman spectroscopy, due to stress relaxation upon cross sectioning of the FGM disc.
