The effect of nanocrystalline formation on the hydrogen storage properties of AB3-base Ml–Mg–Ni multi-phase alloys

Hydrogen storage in Mg–10at.% LaNi5 nanocomposites, synthesized by ball milling at different conditions

“…Mg-LaNi x composites have been investigated widely both in terms of H-storage capacity [16][17][18][19][20][21] and thermodynamics of hydriding [22][23][24]. Certain common properties have been found, including the ability to achieve partial hydrogenation at room temperature and relatively high H-storage capacity (∼4 wt.%).…”

The kinetics of lightweight solid-state hydrogen storage materials: A review

“…A prolonged milling time cannot further decrease the grain size because the minimum size has been reached. In some cases, the nanoscale particle can reduce the hydrogen storage capacity because of the reduction in the intergrain volume [142]. This restriction would contribute to surface contamination, potential inflammation risk and other health concerns.…”

Structure, morphology and hydrogen storage properties of composites prepared by ball milling Ti0.9Zr0.2Mn1.5Cr0.3V0.3Ti0.9Zr0.2Mn1.5Cr0.3V0.3 with La–Mg-based alloy

“…The X-ray diffraction patterns of La 0.7 Mg 0.25 Zr 0.05 (Ni 0.85 Co 0.15 ) 3.5 alloy and ball-milled AB 2 −x wt% AB 3.5 (x = 0, 5, 10) composites are shown in Fig [23], in which the (LaMg)Ni 3 phase tended to transform into the LaNi 5 phase during ball milling process and finally disappeared in the XRD patterns. From the XRD patterns of composite, it was found that the alloying between AB 2 and AB 3.5 alloys took place after ball milling process.…”
