Calorimetric investigation of the hydrogen interaction with Ti0.9Zr0.1Mn1.2V0.1

Alloy Based on Intermetallic (Ti, Zr)(V, Mn, Сr)$_{2-x}$ Obtained Using Titanium Sponge for Hydrogen Sorption

“…It was shown in [4] that partial replacement in the Laves phase TiMn 2 of titanium by zirconium and manganese by vanadium allows to increase the amount of absorbed hydrogen and improve the sorption kinetics; however, the thermal stability of the resulting hydride increases. The authors have shown that an increase in hydrogen capacity occurs due to the redistribution of hydrogen atoms in the tetrahedral voids.…”

Absorption and desorption of hydrogen in Ti1.02Cr1.1Mn0.3Fe0.6RE0.03: experiments, characterization and analytical interpretation using statistical physics treatment

“…In the case of our samples, which belong to the C14 structure, many reports have revealed three types of tetrahedral sites 59 Thus, the apparition of two phases (a and b) during the absorption/desorption phenomenon of hydrogen proves that the two levels of energies are revealed in the chosen model.

Hydrogen Storage Properties of Ti$_{15.4}$Zr$_{30.2}$Mn$_{44}$V$_{5.4}$Сr$_5$ Alloy Produced by Induction and Arc Melting

“…Firstly, in the involved technological process of re-melting, the melt is exposed to high temperatures for short times. Secondly, due to the lower total amount of manganese in the charge (partial replacement by chromium) as compared to the alloy for which the calculations have been made (according to [21] for Ti 0.9 Zr 0.1 Mn 1.2 V 0.1 alloy), the evaporation of manganese is lower than predicted.…”

“…It should be noted that during the charge preparation additional (compared to the nominal composition) 4% wt. of manganese are added, because the authors of [21] studied hydrogen absorption properties of Ti 0.9 Zr 0.1 Mn 1.2 V 0.1 alloy and proved that this amount of manganese can be lost due to the evaporation during melting. The chemical composition of the alloy is determined using energydispersion analysis EDAX (Table 1).…”
