چکیده انگلیسی
Nanocrystalline and amorphous microstructures prepared by rapid solidification (RS) processing are effective in improving the absorption/desorption kinetics of the Mg-based hydrogen storage alloys. In this paper, the as-cast, nanocrystalline and amorphous Mg-5Ni-3La (at.%) alloys were prepared, and effects of microstructure on the hydrogen storage properties of the alloys were studied. The nanocrystalline and amorphous Mg-5Ni-3La (at.%) alloys show better absorption/desorption kinetics than that of the as-cast alloy due to the smaller grain size and more grain boundaries. The values of ÎH (enthalpy) for the Mg-H2 system of the nanocrystalline and amorphous alloys are â74.0 ± 1.2 kJ molâ1 and -66.1 ± 3.4 kJ molâ1, respectively, which are significantly lower compared to that of the as-cast alloy (â77.7 ± 0.3 kJ molâ1).
