✦ Synopsis

We introduce a model for high-angle grain boundaries in the form of a two-dimensional array of compressive forces. Segregation profiles driven by the stress field around the boundary are calculated for several levels of translational order. We find an enhancement of segregation with increasing degree of translational disorder, in agreement with experimental observations.

Grain boundaries in hot-pressed Sic with a sintering additive, ALO,. were investigated using both high-resolution transmission electron microscopy (HRTEM) and energy dispersive X-ray spectroscopy (EDS) with a view to explaining the correlation between high-temperature strength at 1773 K and the grai
