摘要

对长期贮氚后镧镍-5（LaNi

）和铀（U）的老化粉末进行了XRD分析。实验发现:老化镧镍-5的图谱峰有了显著展宽

表现出严重的氚老化效应;当衰变氦-3在1230 K高温消除后

这种展宽也随之消失

表明上述改变主要是由衰变氦-3引起的。相比之下

老化铀的XRD分析发现图谱峰没有明显的展宽

表明铀的氚老化效应要小得多。

Abstract

The XRD researches of tritium aging of U and LaNi5 have been presented. The major effect of tritium exposure present in the XRD patterns for LaNi5 is peak broadening. It was found that the effect disappeared after the helium-3 was removed by 1230 K. On the contrary

the peak broadening of the XRD patterns for aged uranium samples was inconspicuous. The tritium aging effects in the equilibrium desorption isotherms were also slight.
