测定8mol%CeO2-ZrO2在连续冷却中变温t→m的Ms,在Ms以上及以下的等温相变动力学曲线和相变产物的点阵常数等.温相变产物(贝氏体)的点阵常数小于变温马氏体的点阵常数.参照金属材料中的贝氏体相变,建议8mol%CeO2—ZrO2的等温相变为扩散过程控制的贝氏体相变.贝氏体可能在母相晶界形核.
The Ms of the athermal transformation t→m on continuous cooling, the kinetics curve of isothermal transformations above and below Ms and the lattice parameters of the transformation product are measured for 8mol% CeO2-ZrO2. The lattice parameter of the is
