Abstract
The X-ray diffraction method was used to measure the near-surface distribution of the residual stresses of ground alumina and silicon nitride and of quenched alumina. The compressive residual stress due to grinding and quenching improved the bending strength of ceramics. Heavy grinding can introduce flaws in ceramics, reducing the beneficial effect of the compressive stress. The effect of the residual stress on the relation between the bending strength and the defect size was discussed on the basis of fracture mechanics. A model is proposed to assess the effects of the residual stress and the material defect on the bending strength of ceramics.
