Abstract

Nanocrystalline Mg2Ni intermetallic compound was produced from elemental components by induction melting and subsequent mechanical alloying in a planetary ball mill. Then the powder was compacted into bulk samples keeping the nanocrystalline structure. Hydrogen storage capacity of the Mg2Ni bulk samples was found to be of about 1.9 wt.%. The absorption isotherm had a long plateau, corresponding to pressure of 0.1 MPa at the temperature of 553 K. The bulk samples demonstrated high durability after 21 absorption-desorption cycles.
