碩士 === 國立中央大學 === 機械工程研究所 === 94 === This research purpose lies in the influence of manufacturing process and aluminum addition on the structure, appearance and hydriding characteristic of Mg2Ni prepared by IECP. The structure, appearance and hydriding characteristic of Mg2Ni and (Mg2Ni)0.9Al0.1 by the ball milling for 15 hours have been examined by X-ray diffraction(XRD), scanning electron microscopy(SEM), differential scanning calorimetric(DSC) and pressure concentration isothermal(PCI). With the milling time boost, grain refinement of Mg2Ni and (Mg2Ni)0.9Al0.1 results in the phenomenon of broad and weak peak which tends towards amorphous phase then the peak Al3Ni arises from (Mg2Ni)0.9Al0.1 by the ball milling for 15 hours. The agglomeration phenomenon is due to the surface tension increases with fine powder after 15 hours of ball milling. The Mg2Ni prepared by IECP after 15 hours of ball milling activates for an hour to absorb hydrogen 3.0wt.% under 3000C and 40atm. The PCI curve of (Mg2Ni)0.9Al0.1 is by 15 hours of ball milling can be observed dehydriding plateau that pressure is 0.16atm and dehydrogen amount is 0.6wt.% at 2000C.
