利用覆膜法对长期贮存氚的LaNi_5进行了XRD分析.经过实验发现,老化后的LaNi_5的谱峰比新鲜的LaNi_5存在明显的展宽,而经过高温除He处理后,又恢复到新鲜的LaNi_5水准,氚衰变形成的~3He在晶格中居留并在其中形成部分位错亚结构,这可能是导致LaNi_5 XRD衍射峰宽化的主要原因.

The crystal structure of LaNi_5 alloy after longterm storage of tritium was investigated by means of X-ray diffraction (XRD). The results show broadened peaks on the XRD spectra of the specimens compared with that of the as-received ones, indicating clear aging effects of the alloy. The main reason causing the aging effects of the alloy is likely due to the tritium produced ~3He, which might induce dislocation sub-structures in the crystal. The alloy shows the ability to be near fully recovered through high temperature treatment.
