摘要 PdY8.5Ru0.19合金是用于氢同位素分离的膜材料,但涉氚操作后,衰变3He会滞留在合金膜中并形成氦泡,影响其宏观性能。为了解PdY8.5Ru0.19合金膜贮氚老化后,3He在合金膜中的存在形式及分布状态,利用TEM观察分析了贮氚老化45和290 d的PdY8.5Ru0.19合金膜。实验结果表明:在老化45 d的样品中,观察到分布均匀,直径约1 nm的氦泡,同时存在高密度的位错及位错环。在老化290 d的样品中,氦泡直径略微增加,达1.2~1.4 nm,且分布均匀,但位错及位错环密度降低。同时,在合金膜中也观察到因氦泡存在而产生的微裂纹与褶皱,这有可能是导致合金膜贮氚后力学性能下降的原因。
