在室温高压电子显微镜下对变形的立方氧化锆单晶体进行了辐照。作为二次辐射损伤，非本征的棱柱型位错环在{111}面上生长，优先沿位错生长。在约200℃时，环生长得更快，并瞬间转变为具有a/2<110>型Burgers矢量的位错。
Deformed cubic-zirconia single crystals have been irradiated in the high-voltage electron microscope at room temperature. Prismatic dislocation loops of extrinsic character grow on {111} planes as secondary radiation damage, preferentially along dislocations. At about 200°C, the loops grow much faster and instantaneously transform into dislocations with a a/2〈110〉-type Burgers vector.
