Correlation between RBM time, decomposition temperature, MgH2 grain size and activation energy of nanocomposite MgH2/5 wt.% TiMn2 powders. (a) Influence of RBM time on the decomposition temperature, Tdecom for nanocomposite MgH2/5 wt.% TiMn2 powders. The effect of RBM time on MgH2 grain size and activation energy, Ea of nanocomposite MgH2/5 wt.% TiMn2 powders are elucidated in (b).
