Abstract
Mg-x %Mg1.8La0.2Ni(x=10,20 and 30)nanocomposites have been synthesized by high-energy ball milling method.Results of the X-ray diffraction(XRD),transmission electron microscopy(TEM)and selected area electron diffraction(SAED)tests were showed that each composite had a nanocrystalline/amorphous structure,which was beneficial for the improvement of the hydriding and dehydriding properties of Mg.The hydrogen absorption temperature decreased and the hydrogen sorption kinetics were improved.Under the conditions of 423 K and the hydrogen pressure of 2.5MPa,each composite could reach the maximum hydriding capacity within 50 s.
