Abstract
To improve the hydrogen desorption properties of magnesium hydride, the composite material with composition of MgH2-5 at% TiCrMn0.4Fe0.4V0.2 alloy has been prepared by co-milling of MgH2 powder with alloy prepared by vacuum arc remelting method. The effect of additive on MgH2 structure, i.e. crystallite size (D), lattice strain (ɛ), particle size (d), and also hydrogen desorption temperature (T) of obtained composite was evaluated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and differential scanning calorimetry (DSC) methods. It has been shown that the addition of TiCrMn0.4Fe0.4V0.2 alloy to magnesium hydride can yield a finer particle size after mechanical alloying. As a result it leads to a decrease in the temperature of MgH2 hydrogen desorption. The lowest achieved temperature of hydrogen desorption is related to the sample which is mechanically milled for 5 hours, whose temperature is 378° C.
