Abstract
The response of magnesia-partially-stabilized zirconia to cyclic loadi ng was investigated using a purpose-built loading stage, designed to o perate in the vacuum chamber of a scanning electron microscope. Crack tip/microstructural interactions, along with fatigue crack growth rate s were studied and recorded photographically and via a video cassette recorder. For the experimental conditions examined, crack bridging, de flection and closure are discussed as possible mechanisms of fatigue c rack growth resistance.
