摘 要：Martensitic transformation behavior was studied for zirconia containing 4%～10% CeO2 （in mole fraction） by using a dilatometric method. The Ms （Martensite start temperature） decreased near linearly with increasing CeO2. Different transformation modes were observed depending on the composition and cooling rate. ZrO2 containing 6% CeO2 showed isothermal transformation behavior, whereas ZrO2 containing 9% and 10% CeO2 showed athermal transformation behavior. However, ZrO2 containing 8% CeO2 showed either isothermal or athermal transformations behavior depending on the cooling rate. A TTT （Time-Temperature-Transformation） diagram was proposed for ZrO2 containing 8% CeO2.
