摘要
在已证实新搭建的正电子无损检测(NDT)装置系统的可行性和可靠性基础上,为了深入的探讨该套NDT装置在辐照损伤样品中的应用,测试了国产及进口哈氏N合金的Ni+10离子辐照损伤.对比3种不同样品,发现随着辐照剂量的增加,进口电解抛光样品的正电子平均寿命及S参数变化相对小,表明辐照产生的缺陷较少,该样品具有较好的抗辐照性能.
Based on the feasibility and reliability of the positron NDT system, in order to investigate the application of the NDT system in the irradiated samples, the alloy of Ni ＋ 10 ion irradiation damage was tested. By comparing the three different samples, we found that with increase of radiation dose, the changes of positron average and the Sparameters of the imported electrolytic polishing samples were small, which showed that the sample has good anti -irradiation performance.
