作者发现在ZrO 2 -Y2 O3陶瓷中，马氏体相变的等温传播，从四斜向单斜转变，这是通过类似于钢中下贝氏体的机制发生的。单斜相的这种等温扩展似乎是由氧离子扩散或存在于四方晶格（一种畸变的CaF 2结构）中的所谓Frenkel型缺陷与氧离子之间的相互作用控制的。
The authors have found in ZrO 2 -Y 2 O 3 ceramics, an isothermal propagation of martensitic transformation, tetragonal to monoclinic, which occurred by means of a similar mechanism to generate the lower bainite in steels. This isothermal propagation of monoclinic phase appears to be controlled by the oxygen-ion diffusion or the interaction be- tween so-called Frenkel type defects and oxygen ions which existed in the tetragonal lattice (a distorted CaF 2 structure) of
