Regularities of hydrogen interaction with multicomponent Ti(Zr)–Mn–V Laves phase alloys

Hydrogenation properties and microstructure of Ti–Mn-based alloys for hybrid hydrogen storage vessel

“…It was found that these alloys contained C14 Laves (hexagonal MgZn 2 structure) and BCC phase as the main phases and FCC phase as a minor phase from the XRD peaks and the Rietveld refinement. Such multi-phase precipitated in the large composition range of the Ti-V-Mn alloys [11,12]. The experiment points of Ti0.5V0.5Mn were indicated by dots, while the upper curve was the calculated profile by the Rietveld refinement as shown in Fig.…”

“…In addition, the hydrogenation properties such as the plateau and hysteresis pressure can be easily improved by substitution of the transition metals. The Ti-Mnbased alloy has been extensively investigated about the effects of the hydrogen properties on substitution of the transition metals [6][7][8][9][10][11][12][13][14][15][16][17][18], however, the hydrogen absorption/desorption behavior and the microstructure of ternary Ti-X-Mn (X: transition metal) alloys has not been well defined.…”

“…We selected V as the third element of Ti-X-Mn alloys because the hydrogen absorption capacity and the hydrogen desorption plateau pressure are influenced by the V addition for the Ti-Mnbased alloys [11][12][13][14][15]. The Ti-V-Mn alloys, which can control the plateau pressure and the effective hydrogen capacity, are one of the suitable alloys for the hybrid hydrogen storage vessel.…”

High-pressure hydrogenation properties of Ti–V–Mn alloy for hybrid hydrogen storage vessel

“…The Ti-Mn-based alloys have been investigated to improve the effective hydrogen capacity, the plateau pressure, the hysteresis pressure, the hydriding-dehydriding kinetics, the cycle property, and the standard enthalpy of hydride formation smaller than 30 kJ/mol by substituting transition metals for Ti in the A site and Mn in the B site [4][5][6][7][8][9][10][11][12]. Particularly, the hydrogen capacity and the plateau pressure were influenced by V substitution into the Ti-Mn-based alloys [9][10][11][12][13][14][15][16].…”

Structure and hydrogen absorbing properties of ScCrMn alloy

“…The Ti-and Zr-based Laves phase alloys have been extensively studied on hydrogen storage properties due to their fast kinetics, high storage capacity, easy activation, moderate working conditions and existence of wide ranges of homogeneity [1][2][3][4]. Among these alloys, the Ti x Zr 1−x MnCr alloys have been studied recently [5,6].…”
