Phase analysis and distribution of X between primary solid solution Mg–Ni–X and Mg2Ni–X compound was carried out in stabilization annealed samples before hydrogen charging and in hydrided state. In the both states, it was found that X prefers Mg2Ni–X to Mg–Ni–X solid solution, and that the preference is stronger in the hydrided state. The effect is more pronounced for elements X from the 13th group. Suggested explanation was based on influence of X on the formation enthalpy of hydrides. It was observed that In increases the hydrogen storage capacity of the eutectic mixture. The most likely explanation is based on a strong segregation of In to phase Mg2Ni–X, and on a weak tendency of In to form phases with Mg and Ni.
