“…In alternate growth rings, the dark regions corresponded to the stained amorphous lamella whereas the semicrystalline lamella was much lighter. For ball milled starch at 1 h, it showed the development of a radially oriented fibrillar network structure and central cavity attributing to melting of partial starch crystallites (Singh, Shim, & Cho, 2007). The treated starch granules at 3 h lost their intact shapes and alternate growth rings, and small amount of exudates were leached.…”

“…Increase of ball milling time resulted in the increase in lattice strain and the decrease in crystallite size, which in turn increased subgrain boundaries. These contamination and microstructural changes caused an important decrease in the hydrogen storage capacity [47].…”

It has recently been shown that Severe Plastic Deformation (SPD) techniques could be used to obtain nanostructured metal hydrides with enhanced hydrogen sorption properties. In this paper we review the different SPD techniques used on metal hydrides and present some specific cases of the effect of cold rolling on the hydrogen storage properties and crystal structure of various types of metal hydrides such as magnesium-based alloys and body centered cubic (BCC) alloys. Results show that generally cold rolling is as effective as ball milling to enhance hydrogen sorption kinetics. However, for some alloys such as TiV 0.9 Mn 1.1 alloy ball milling and cold rolling have detrimental effect on hydrogen capacity. The exact mechanism responsible for the change in hydrogenation properties may not be the same for ball milling and cold rolling. Nevertheless, particle size reduction and texture seems to play a leading role in the hydrogen sorption enhancement of cold rolled metal hydrides.

“…TiCrV alloy with BCC structure has been studied for years as a promising hydrogen storage material [6][7][8][9][10][11][12][13][14][15]. It has two plateau pressures, where only the upper plateau pressure area can be used for reversible hydrogen storage in normal condition.…”

High-pressure metal hydride (MH) tank is a possible hydrogen storage system for fuel cell vehicles. The merit of the high-pressure MH tank system is improved by the use of a metal hydride with high dissociation pressure. In this study, TiCrV and TiCrVMo alloys with BCC structure has been developed for the high-pressure MH tank system. The developed TiCrVMo alloy shows 2.4 mass% of effective hydrogen capacity between 0.1 MPa and 33 MPa at 298 K, which has a dissociation pressure of 2.3 MPa at 298 K. By investigating the dissociation pressures of the synthesized metal hydrides, it is found that Mo has a special effect to increase dissociation pressure of the metal hydrides. This effect is probably attributed to the large bulk modulus of Mo compared to other elements.
