Lukashev, S. Klyamkin, B. Tarasov] The hydriding properties of magnesium have been studied at temperatures from 670 to 720 K and pressures from 19 to 55 MPa. The results suggest that the hydrogen pressure and hydrogen absorption/desorption cycles influence the nucleation process in the Mg-H2 system. Using mechanical activation of MgH2 + graphite and MgH2 + graphene nanofiber (GNF) mixtures, we have prepared MgH2/graphite and MgH2/NGF composites. Investigation of their hydriding properties has shown that mechanical activation markedly accelerates hydrogen sorption/desorption processes and reduces the thermal stability of the material compared to unmilled magnesium hydride. The mechanisms of hydrogen desorption from the composites in different stages of their thermal decomposition are analyzed. Pleiades Publishing, Inc., 2006 Lukashev R.
