“…Precipitation of ɳ-carbide type oxide A 3 B 3 O, was reported in as-cast Zr 0.75 Ti 0.25 MnV alloy [36] and also observed in a number of studies on other Ti-Mn based alloys [24,25,33,37]. The detrimental effect of oxygen on the microstructure and therefore homogeneity of the C14…”

“…Varying the alloy composition and the elemental substitution allowed the properties of Ti-V-Mn alloys to be tailored, although beneficial effects of these modifications appear difficult to predict. For example, whilst increasing V content improved the activation process and encouraged the formation of BCC phase, its substitution for Ti or Mn led to opposite effects on the hydrogen absorption plateau pressure [23,25,[31][32][33].…”

“…Investigating the kinetic and sorption parameters of hydrogenation of AB 2 -type intermetallics, Pickering et al [16] found that the best kinetic and sorption parameters were observed for alloys in which the Laves phase coexists with a bcc solid solution that exhibits similar reaction kinetics and practically identical stability of the hydride. A new concept for the production of high hydrogen capacity alloys, called "Laves phase-related bcc solid solution", was proposed.…”

The phase composition and crystal structures of heterophase Ti-Zr-Mn-V alloys were studied by scanning electron microscopy and X-ray diffraction. The structure of the as-cast and annealed alloys consisted of a Laves phase and a bcc solid solution. It is shown that the alloys interact with hydrogen at room temperature and a pressure of 0.23 MPa with an incubation period of 6-10 min and a duration of the absorption process of 10 min. The resulting hydrogen sorption capacity was more than 2 wt.%. Additional processing of the obtained hydrides could increase the hydrogen sorption capacity.

“…However, the industrial applications of V-Ti-based hydrogen storage alloys were restricted due to poor kinetic characteristics, low hydrogen desorption capacity at room temperature and high costs [6][7][8][9]. The effective method of reducing their costs and improving the hydrogen storage properties is the addition of Cr and Fe elements into the V-Ti-based alloys [10][11][12][13].…”

The microstructure, crystal structure, hydrogen storage properties and thermal stabilities of as-cast and annealed V40Ti20Cr32Fe8 alloy prepared by arc-melting were studied in this work. It was confirmed that both as-cast and annealed (973 K/72 hrs) V40Ti20Cr32Fe8 alloys are body-centered cubic (bcc) main phase and C14-typed Laves secondary (Cr2Ti). Experimetnal results show that the maximum hydrogen absorption capacities of as-cast V40Ti20Cr32Fe8 alloy at 303 K, 333 K and 363 K are about 2.25 wt.%, 1.75 wt.% and 1.12 wt.%, while that of the annealed alloy at 303 K, 333 K and 363 K are about 2.26 wt.%, 1.76 wt.% and 1.26 wt.%, respectively. The maximum hydrogen desorption capacities of as-cast V40Ti20Cr32Fe8 alloy at 303 K, 333 K and 363 K are about 1.15 wt.%, 0.89 wt.% and 0.60 wt.%, while that of the annealed alloy at 303 K, 333 K and 363 K are about 1.22 wt.%, 0.90 wt.% and 0.61 wt.%, respectively. It is indicated that hydrogen absorption/desorption kinetics of the V-Ti-Cr-Fe alloy is greatly improved by heat treatment.
