研究了含1.9摩尔%氧化钇的粗晶氧化锆试样在中温等温或非等温冷却下产生的马氏体形态。等温马氏体表现出良好的定义薄板，而非热马氏体形成的透镜和金字塔形状。薄板状和透镜状马氏体在{103}（c）附近具有与唯象理论一致的惯习面，而金字塔状马氏体则是由四种变体组成的应变调节结构。(c)2006 Elsevier B. V.保留所有权利。
Morphology was studied on martensite produced either isothermally at an intermediate temperature or athermally by subzero cooling of coarse-grained zirconia specimens containing 1.9 mol% yttria. The isothermal martensite exhibited well defined thin plates, while athermal martensites formed both in lens and pyramid shapes. The thin-plate and lens-shaped martensites had habit planes near {103}(c) in agreement with phenomenological theory, while the pyramidal shape appears to be a strain accommodation structure consisting of four variants.
