摘要: 用PAT、CEMS、SEM和TEM分析观测了HIRFL提供的能量为几十MeV到几百MeV的碳离子在Ni、马氏体时效不锈钢、HT—9铁素体钢和316L不锈钢中引起的辐照效应,包括辐照引起的偏析、脱溶、相变和肿胀,以及辐照肿胀随辐照温度的变化关系,研究了510MeV的碳离子在高纯Ni中的损伤分布,并给出了95MeV的Ar离子模拟宇宙射线在宇宙飞行器中引起数字半导体器件“软故障”的最近结果。 The radiation effects were studied by means of PAT, CEMS, SEM and TEM in nickel,martensitic ageing stainless steel, ferrite steel HT-9 and stainless steel 316L induced by carbon ionswith energy of tens of MeV to hundreds of MeV delivered by HIRFL. It includes segregate,preciptale, phase change and void swelling, as well as temperature-relativity of the irradiationswelling. The damage distribution was also studied in nickel irradiated by 510MeV C~(6+). And the recentresults of Ar ions ...
