  • Influence of the zirconia transformation on the thermal ...

    2011-9-23 · During a heating–cooling cycle, zirconia (ZrO2) undergoes a martensitic transformation from monoclinic to tetragonal structure phases, which presents special hysteresis loop in the dilatometry curve at temperatures between 800 and 1100 °C. Monoclinic zirconia (m-ZrO2) particles reinforced ceramic matrix composites not always present this behavior.
