Abstract
The rate of the transformation from the metastable tetragonal to the monocl inic phase of ZrO2 was measured in air from 850 degrees C to 1000 degrees C by neutron diffraction. This rate was found to be temperature dependent, a nd its measured values were considerably lower then those reported previous ly. The kinetics of this phase transformation is discussed in terms of a mo dified 'crystallite growth-martensitic transformation model' that includes the distribution of crystallite sizes.
