Abstract

Microstructural development associated with diffusionless phase transformation was investigated in sintered ZrO₂-10-60 mol% CeO₂ ceramics cooled rapidly from a high temperature, using TEM and XRD techniques. The results show that (112) reflections appeared and a domain structure was found in ZrO₂-20-40 mol% CeO₂ samples, which is a result of c-t′ diffusionless transition, while the structure of the ZrO₂-60 mol% CeO₂ sample was fully stabilized zirconia, in which no forbidden reflections of c-ZrO₂ appeared. Finally, plate martensite and lath martensite structure were found in the ZrO₂-10 mol% CeO₂ sample; the former is the tetragonal phase with internal twins and the latter is the twinned monoclinic phase.
