摘要：

Fracture toughness and crack growth resistance (R-curve) behavior of several microstructures of 70%Si3N4-30%BAS composite are characterized using the indentation and modified compact tension methods, at room temperature. Both the whisker morphology and matrix properties contribute to the fracture resistance behavior. Crack deflection, whisker bridging and pullout are regarded as the dominant toughening mechanisms.
