Experiment N2 - o microstructural characteristics, particle morphology and size, have been examined with respect to toughening by crack deflection. Particle morphology effects were evaluated in a series of hot-pressed silicon nitrides comprised of rod-shaped grains of various aspect ratios and a barium- silicate glass ceramic containing spherulites. Lithium-alumina-silicate glass ceramics containing Li2Si10s lath-shaped crystals were studied for particle size effects. Independent measures of the fracture toughness and the crack deflection process were performed and results were correlated with a crack deflection model UR - https://drive.google.com/file/d/1WaaGEUdyLQi1XVOvHWkL6v60yG-Rw1n3/view?usp=drivesdk ER -
