![عکس صفحه اول مقاله: In-situ Observation of Point Defect and Precipitate Evolvement of CLAM Steel under Electron Irradiation In-situ Observation of Point Defect and Precipitate Evolvement of CLAM Steel under Electron Irradiation](/preview/png/1556137.png)
The point defect and precipitate evolution of China low activation martensitic steel (CLAM) under electron beam irradiation were characterized by high voltage electron microscopy. The process was recorded in-situ on electron-sensitive films. The irradiation dose rate was 1.78 × 10−3 dpa/s and the highest dose was 2.12 dpa/s. Irradiation introduced dislocation loops into the sub-grain, which increased density when the irradiation dose was increased from 0.53 dpa to 1.59 dpa at 723 K. The precipitate, found to be an M6C type, was irradiated at 773 K at the [011] plane direction. The precipitate morphology and structure were unchanged when the irradiation dose was increased to 2.12 dpa. Compared with the irradiation at 723 K in the sub-grain, no other defects were generated at the nearby grain boundary at 773 K.
