Crack deflection processes—II. Experiment

Creators

Abstract

Two 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 bariumsilicate glass ceramic containing spherulites. Lithium-alumino-silicate glass ceramics containing Li_2Si_2O_5 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.
