| dc.description.abstractEn | An Mg-10wt%Ni-5wt%Fe-5wt%Ti sample was prepared by mechanical grinding under H<sub>2</sub> (reactive mechanical grinding) using a planetary ball mill. The phases and their weight percentages were analyzed with the Full Proof program from the XRD patterns of the Mg-10Ni-5Fe-5Ti samples after reactive mechanical grinding and after dehydriding at the seventh cycle. The Mg-10Ni-5Fe-5Ti sample after reactive mechanical grinding contained Mg, TiH<sub>2</sub>, MgH<sub>2</sub>, and Ni phases, and the sample dehydrided at the seventh cycle contained Mg, TiH<sub>2</sub>, MgO, Mg<sub>2</sub>Ni, and Fe phases. The prepared Mg-10Ni-5Fe-5Ti sample had an effective hydrogen-storage capacity larger than 5 wt%H. The activated Mg-10Ni-5Fe-5Ti sample absorbed 5.31 and 5.51 wt%H for 5 and 60 min, respectively, at 573 K under 12 bar H<sub>2</sub> and desorbed 1.58, 3.64, and 5.18 wt%H for 10, 30, and 60 min, respectively, at 573 K under 1.0 bar H<sub>2</sub>. The effects of reactive mechanical grinding, hydriding-dehydriding cycling, and addition of transition elements Ni, Fe, and Ti were discussed. | |
