摘要: With the aim to decrease temperature and improve kinetics of decomposition MgH2 stoichiometric hydride, we study possibility its complex alloying with 3 at.% Al + Ni 7 Ti performed help mechanochemical synthesis. It is shown that, as a result addition Al, Ni, magnesium, thermal resistance hydride phase mechanical alloy obtained by reactive decreases and, hence, onset hydrogen desorption from 320°C (for without Ti) 280°C. We do not detect any in equilibrium under constant pressure 1 bar reactor, which may serve an indication loss thermodynamic stability alloying. that mainly improved Ti, whereas contribution negligible.
