Abstract
Starting from a mixture of Mg and Ni with an atomic ration of 2:1 and using a planetary ball mill, we have successfully elaborated a Mg2Ni rich nanocomposite material formed by the Mg2Ni phase, some residual Ni and an amorphous phase. The synthesis of this composite proceeded at milling intensities 10 and 7, corresponding respectively to 10 and 3.5 W g-1 shock power, respectively after 4 and 18 h. The best hydrogen absorption capacity reported, 3.53 wt % (3.75 H/mole), is for the composite synthesized at 3.5 W g-1 shock power and 24 h mechanical alloying time. These mechanical alloying time and hydrogen absorption capacity are better than those reported up today [18,3].
