It is revealed that introduction of insoluble components in magnesium leads to temperature decrease desorption deuterium. Samples of systems have nano/amorphous state. The step kind of curve dependence of temperature of a maximum of the thermoactivated allocation дейтерия from the investigated composites on the basis of Mg testifies to presence of two different structural conditions for systems depending on a parity of components. Thus surpassing role is defined by one of a component (Mg or Ti, V, Zr). The parity a component (stoichiometry), testifies in favour of possibility of formation of chemical compounds from components which do not co-operate in usual conditions. Laws of behaviour of hydrogen in magnesium connections depending on type, concentration of the additive, structure, construct model of behaviour of hydrogen in alloys - stores of hydrogen on the basis of magnesium are based. The made composites represent a substance which consists from hydride formation a magnesium basis and inclusion at it segregation in the form of tape formations from insoluble in magnesium a component. Thus between tape inclusions and a matrix transitive formation which has an amorphous condition is formed. Presence of an amorphous condition provides high диффузную mobility of hydrogen in composites, saturation of a matrix by hydrogen. Temperature decrease desorption hydrogen is provided with channels which are formed by insoluble components in magnesium. The obtained data testifies to perspective of search of materials - hydrogen stores in which structure there are chemical elements which do not co-operate with components of composites (nanogenerate elements). Presence of such elements reduces temperature desorption hydrogen. The further researches directed on search of more effective structures of composites with comprehensible in the temperature desorption hydrogen, kinetics sorption - desorption hydrogen etc. are necessary.
