The Mg50Ni45Ti5 alloy for the hydrogen storage is prepared by mechanical alloying. The structure and the morphology of the alloy are characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). These techniques esteemed that this alloy is a good candidate for hydrogen storage, since it is both nanocristallin and dsuctile. This is confirmed by the modeling of the hydrogen equilibrium pressure-composition-temperature (PCT) relationships for this alloy. These isotherms were experimentally generated for three temperatures 313 K, 327 K and 340 K and modeled through the statistical physics using the monolayer model with two energies levels. Energetic, steric and thermodynamic studies were released thanks to this model which proved the efficiency and the security of this alloy to the storage of hydrogen.
