Abstract

The aluminum alloy SAV-1 was studied before and after inducing the radiation damage by means of neutrons with the following values of doses: 1016 - 1018 n/сm2. The measurements were carried out by neutron diffraction methods to analyze the correlation of the structural state with the results of measurements of the strength of the sample obtained using a loading machine. It was found that the changes in the strength characteristics of aluminum alloys were associated with modifications at the grain boundary during irradiation of the samples. Thus, the obtained experimental data allows us to conclude that the SAV-1 alloy represents an interstitial solid solution, and the strength of the alloy changes nonlinearly depending on the radiation dose.

中子辐照对SAV-1铝合金组织和强度的影响

对SAV-1铝合金进行了剂量为1016 ~ 1018 n/ m2的中子辐照损伤前后的实验研究。用中子衍射法对试样的结构状态进行了测量，分析了结构状态与试样强度测量结果的相关性。结果表明，辐照过程中铝合金强度特性的变化与晶界的变化有关。因此，得到的实验数据使我们得出结论，SAV-1合金为间隙固溶体，合金的强度随辐射剂量呈非线性变化。
