摘要: 為了研究低活化馬氏體CLAM鋼的抗輻照腫脹性能,在450℃下對CLAM鋼進行大劑量高能電子輻照的原位動態實驗.利用超高壓透射電子顯微鏡觀察發現,CLAM鋼中產生了大量的間隙原子型位錯環和多面體形狀的輻照空洞.分析了它們的形核和長大規律以及相關機制.計算表明,CLAM鋼在高能電子輻照下的最大腫脹率為0.26%,具有較好的抗輻照腫脹性能.

Abstract: To research the resistance of China low activation martensitic (CLAM) steel to irradiation swelling, the microstructure of CLAM steel irradiated by high energy elections at 450℃ was in-situ observed on a high voltage electron microscope. The results indicate that a lot of voids and dislocation loops form by irradiation. The dependence of the amount and size of these damages on the irradiation dose are evaluated and discussed. The irradiation swelling is about 0.26% and thus CLAM steel is considered as a material with high resistance to swelling.
