Abstract
Using a planetary ball mill and starting from a mixture of Mg and Ni with an atomic ration of 2:1, we have successfully elaborated a nanocomposite material formed by the Mg2Ni phase in high proportion, some residual Ni and an amorphous phase. The synthesis of this composite proceeded at milling intensities 7 and 10, corresponding respectively to 3.5 and 10 W g-1 shock power, respectively after 18 and 4 h. The best hydrogen absorption capacity reported, 3.75 H mole-1 (3.53 wt.%), is for the composite synthesized for 24 h at 3.5 W g-1 shock power.
