    Mg shows a high hydrogen storage amount of 7.6 mass%, however formation rate of MgH2 is very slow. Conventional approaches were proposed such as adding a catalyst or sub-micronization of Mg powder. Careful observation of the hydrogenated microstructure of Mg revealed that in addition to MgH2 (sur) produced on the surface layer, MgH2 (int) was also produced inside unreacted Mg It was found that the growth of this MgH2 (int) affected the Mg matrix, and the nucleation frequency was affected by the hydrogen supply and defects.

    It is found that the growth rate constants of Mg2Cu in Mg/Cu super-laminate composites (SLCs) is approximately ten to the second - forth order larger than that of Mg-Cu diffusion couples. It is because that extreme severe plastic deformation such as accumulative roll bonding (ARB) with more than 5 cycles can enhance atomic diffusion and promote solid-state reactions because of an increase in the density of lattice defects such as vacancies, dislocations and grain boundaries. It is also found that hydrogenation of Mg was dominant in Mg/Cu SLCs during initial hydrogenation of Mg/Cu SLCs when Mg was thick, whereas that of Mg2Cu was dominant in Mg/Cu SLCs when Mg was thin. It is considered that the average thickness of Mg + Cu layers in as-rolled Mg/Cu SLCs as a function of ARB cycles has a large influence on initial hydrogenation properties and microstructure formation processes.
