Abstract
R-Curve behaviour of alumina and magnesia partially stabilized-zirconi a (PSZ) has been investigated. The influence of precracking procedure (notch or pop-in precrack), the environment, the temperature and micro structure has been studied. Alumina and high monoclinic phase content PSZ show similar behaviour, different from that observed for high tetr agonal phase content PSZ. The results are discussed in terms of micros tructure, fracture mode and toughening mechanisms.
