Název v původním jazyce

Hydrogen storage behavior of Mg/Ni layered nanostructured composite materials produced by accumulative fold-forging

Popis výsledku v původním jazyce

An advanced and newly developed severe plastic deformation (SPD) method called accumulative fold-forging (AFF) was applied to produce layered nanostructured MgNi alloys exhibiting superior hydrogen storage capacity. Microstructural developments and storage properties were characterized in depth to correlate the structure and performance of this advanced material. The enhanced hydrogen storage performance of the magnesium-based layered composite material was investigated in comparison to the pristine state by conducting hydrogenation and dehydrogenation testing. It was also shown that the hydrogen uptake and release characteristics can be controlled by adjusting the layered structure or the Mg: Ni stoichiometry ratio. Refining the grain structure of the magnesium alloy down to the nano-scale range by applying high cycles AFF consolidation to promote creation of multi-million nanometric interfaces led to superior storage performance.
