The intermetallic compound Mg2Ni was mechanically ground under a hydrogen atmosphere. Its hydrogen content reaches 1.6 wt.% (Mg2NiH1.8) without changing the crystal structure of the matrix Mg2Ni phase, and the dehydriding reaction starts at around 440 K. Its properties are most likely to originate from the formation of a nano-scale composite material which is composed of the crystalline matrix phase and the disordered interface phase.
