Abstract
An automated Raman microscope system has been used to collect mapped Raman data from a Goodfellow 3% MgO stabilized zirconia ceramic tile. The data have been transformed to produce images which show the relative concentrations and distributions of the monoclinic and tetragonal phases in the mapped areas. The images reveal concentrations of the monoclinic phase at grain boundaries. Regions surrounding indents in the tile created with a Vickers hardness tester, were also mapped to reveal the extent and pattern of stress-induced phase transformation. A Raman map was also generated from an area before and after indentation. Comparison of the Raman images with the optical white light images reveals a relationship between the pattern of grain boundaries on the sample and the distribution of transformed material.
