Summary

The crystallographic orientation of grains and local strain in ceramics were determined by Raman microspectroscopy. C-axis orientation of alumina grain was found by fitting a theoretical function to measured intensity of polarized scattering at 418 cm-1 and 645 cm-1. Local strain parallel and perpendicular to the c-axis of sapphire was also found based on the shift of two Raman lines in four-point bending. A linear relation between stress and peak shift was noted, which was consistent with theoretical prediction. Crystallographic orientation and residual strain can thus be simultaneously evaluated using Raman spectroscopy.
