- 論文の詳細を見る
The process of hydrogen-induced amorphization in the L1_2 type intermetallic compound Zr_3Al has been investigated by x-ray diffraction and transmission electron microscopy. Then, it has been compared with that of the isomorphous Zr_3In. Zr_3Al amorphizes below about 500 K where the decomposition of it into ZrH_2 and Al is substantially suppressed in contrast to Zr_3In. Almost complete disordering precedes the onset of amorphization in the same way as irradiation-induced amorphization of this compound. The DSC result suggests that hydrogen atoms in a-Zr_3AlH_4 are trapped tightly in comparison with those in a-RM_2H_x (R=a rare earth metal, M=Fe, Co, Ni) prepared by hydrogenation.
