The variation of the structural parameters, including the interplane distanced (III), the amount of tetragonal phaset, and the size of regions of coherent scattering, in the process of the tetragonal-monoclinic transformation in cooling of a ZrO2−Y2O3−Al2O3 ceramic material with a variable phase composition from the sintering temperature (1500–1700°C) is considered. It is established that the dependences of the interplane distancesd (III) on the temperature behave nonlinearly in the temperature range of the phase transformation. It is shown from the data of an x-ray analysis that the tetragonal-monoclinic phase transformation occurs in at least two stages, one of which consists in rhombic distortion of the lattice and the other of which results in formation of a monoclinic phase. The suggested model is used to construct an elementary cell of the monoclinic phase and interpret the fracture behavior of a transformation-toughened ceramic material.
