The thermodynamic properties of Ti–Zr–Cr–Mn Laves phase alloys

Advanced high-pressure metal hydride fabricated via Ti–Cr–Mn alloys for hybrid tank

“…Lee et al [21] found that the hydrogen capacity of TieCr alloy improved while the hydrogenation pressure plateau decreased when Cr was replaced by larger V atoms. In TieZreCreMn Laves phase alloys, Park et al [22] also observed that the lattice parameter and hydrogen capacity increased, while the decomposition plateau decreased when Ti was substituted by larger Zr atoms. Beeri et al [23] partially substituted some Cr by Mn to form TiCrMn alloy, the DH d has been decreased to 19.6 kJ/mol H 2 , which was close to the target value of high-pressure alloy (20 kJ/mol H 2 ).…”

Thermodynamics of hydrogenation for Ti1−xZrxMnCr Laves phase alloys

“…Therefore, extensive substitution studies have been carried out on the promising Ti 1−x Zr x Mn 2−y M y (M = V, Cr, Ni, Fe, etc.) system [19][20][21][22][23]. Among these alloys, particular attention has been paid to the Ti 1−x Zr x Mn 2−y Cr y Laves phase alloys, due to their high storage capacity and low hysteresis for hydrogenation [19][20][21].…”

Ti–V–Mn based alloys for hydrogen compression system

“…The Ti-based alloys were studied extensively, because of their potential great sorption capacity at ambient temperature (∼2 wt.%) with high reactivity rates [4][5][6][7][8][9][10][11][12]. Moreover, the position of the absorption and desorption plateaus (from 2 to 10 atm) made them good candidates for the compressor project.…”
