Abstract The hydrogen absorption properties of UThTiZr alloys were investigated for the purpose of developing a new hydride nuclear fuel. The alloy specimens consisted of two phases before hydrogenation, namely a Th phase and a UTiZr phase. The phases in the hydrogenated alloys depended strongly on their history. Upon hydrogenation at low hydrogen pressure above 1073 K, the ThZr 2 H 6 phase grew
摘要 为开发新型氢化物核燃料,研究了UThTiZr合金的吸氢性能。合金试样在氢化前由两相组成,即Th相和UTiZr相。氢化合金中的相在很大程度上取决于它们的历史。在高于 1073 K 的低氢压下加氢时,由于在 TiZrH 体系中形成了稳定的三元氢化物,ThZr 2 H 6 相生长得相当好但不够充分。这也干扰了UTi 2 H 5 的形成。尽管因此没有获得均相,但获得了没有崩解的氢化物。
