A technique has been developed for forming bicrystals of alumina with controlled grain boundary orientation by pressure-sintering in vacuo. Bicrystals with tilt misorientations prepared by this technique have been tested in compressive shear and the stress-strain relationship determined. Bicrystal fracture strengths at several temperatures are reported. The microstructural features of the fractured crystal boundaries were examined and related to the observed mechanical behavior.
