are composed of LaNi5 and LaNi3 phase. The hydrogen absorption/desorption pressure of the alloy increases, so does the slope of plateau, and the plateau becomes broad first and narrow again as Mg content... were measured on RINT-1100 type X-ray diffraction analyzer of Japan with Cu radiation. AMC GAS REACTION CONTROLLER of America was used to test PCI curves for reflecting the hydrogen absorption......

Variation of hydrogen absorption enthalpy of Mg-Ni amorphous alloys with Ni content and its effect on self-discharge Abstract: The hydrogen absorption enthalpies of Mg.... The result demonstrates that the model can be used in the evaluation of the hydrogen absorption enthalpies of amorphous alloys. Through investigating the enthalpies varied with Ni content, it can......
; low neutron absorption cross section[1-2]. Zirconium hydride with high hydrogen content (H/Zr＞1.5) is one of the most ideal moderators used in space nuclear reactors[3-4]. The nuclear, physical... change of oxygen absorption is observed below 718 ℃. It can be concluded that hydrogen released from zirconium hydride in the mixed gas of helium and oxygen has no influence on oxygen consumption......

by melt-spinning technology. The structures of the alloys were studied by XRD, SEM and HRTEM. The hydrogen absorption/desorption kinetics and the electrochemical performances of the alloys were measured. The results show that no amorphous phase forms in the as-spun Co-free alloy, but the as-spun alloys containing Co show a certain amount of amorphous phase. The hydrogen absorption capacities......
