چکیده انگلیسی
Nanocrystalline Mg and Mg-10Ti hydrogen-storage alloys were prepared by reactive mechanical grinding combining with hydrogen pulverization. The synthesis was done at room temperature under 3Â atm of hydrogen using a planetary ball milling device for 6Â h. The surface area of the Mg-10Ti alloy was further increased from 0.61 to 6.16Â m2/g when the milled alloy was pulverized by hydrogenation at 350 ÌC. The morphological and microstructural characteristics were investigated by scanning electron microscopy, X-ray diffraction, and transmission electron microscopy. After the reactive mechanical grinding and hydrogen pulverization, the particle size of the powder was reduced and magnesium hydride was formed. The addition of titanium efficiently inhibited the oxidation of magnesium during alloying process. Furthermore, the hydrogen storage characterization revealed that the addition of titanium improved the hydrogen absorption capacity of 3.63Â wt% as compared with that of Mg (3.36Â wt%). Mg-10Ti alloy has an improved absorption capacity and decreased hysteresis.
