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.
