It has been established that brittleness and reliability of ceramics can be improved by a stress-triggered tetragonal (T) to monoclinic (M) transformation in zirconia termed transformation toughening. The T [r arrow] M transformation is not only influenced by such intrinsic factors as the variety and amount of stabilizers, grain size and morphology of T phase, but can be affected by the cooling rate as well. A previous study by Tsubadin, using a dilation experiment to determine the effect of thermal cycling on the T [r arrow] M transformation in partially stabilized zirconia suggested that sintering temperature determined the role of thermal cycling, while the underlying cause still remains ambiguous. The intent of the present paper is to reinvestigate the effect of thermal cycling on the T [r arrow] M transition in a hot pressed ZrO[sub 2](2%y[sub 2]O[sub 3]) ceramic, using a high temperature x-ray diffractometer, and rationalize the experimental results from the viewpoint of thermodynamics.
