The amorphous phase is formed in (Mg_1-xAl_x)Ni with x = 0-0.2, while the crystalline phase of a CsCl-type cubic structure is formed with x = 0.3-0.5 even in the as-mechanically-alloyed states. The total radial distribution functions for X-ray and neutron diffractions show that deuterium in MgNi, that is, x = 0, occupies the interstitial tetrahedral site composed of nearly 2Mg2Ni. Electrochemical P-C (hydrogen pressure-composition) isotherm measurements revealed that there is an obvious miscibility-gap pressure higher than 10^-4 MPa at room temperature even in MgNi, and that the pressure increases by the A1 substitution.
