Summary

The structural changes in the vicinity of indentations in Y-PSZ were investigated by microraman spectroscopy and micro-focus synchroton radiation diffraction. It is shown that some Raman band intensities are strongly susceptible to the orientation relative to a polarised laser beam, both for monoclinic and tetragonal phase bands. This feature was used to demonstrate a preferred orientation of both t- and m-grains around indentations. The orientation direction rotates along the edges of an indent, which is related to the curvature of stress field lines.

This feature is also important for the evaluation of relative proportions of t- and m-phase in partially transformed ZrO2 and is a potential source for large errors.
