Recent evidence is summarized showing that the tetragonal (t) {yields} monoclinic (m) martensitic transformation in ZrO{sub 2} can occur thermoelastically in certain ZrO{sub 2{minus}} containing ceramics, and that microcracking accompanying the transformation is more common than had previously been recognized. The implications of these new data for the conditions under which the stress-induced transformation is irreversible, and for the particle size dependence of the transformation start (M{sub s}) temperature, are discussed.
