Correlation between hydrogen absorption properties and homogeneity of Ti–Cr–V alloys

Improvement of cyclic durability of BCC structured Ti–Cr–V alloys

“…These small peaks shown along with broadening suggest a secondary phase, which cannot absorb or desorb hydrogen reversibly. Arashima et al [7] have reported that floating zone melting improves the homogeneity of Ti-Cr-V alloys and that the rechargeable hydrogen capacity is increased by this process. The initial hydrogen capacity of the WQ and FZ alloys prepared in this study was the same but degradation of hydrogen transfer of the FZ alloy was smaller than that of the WQ alloy.…”

Mechanically driven b.c.c. TiCr alloy and its hydrogen solubility

“…solid solution alloys have shown many attractive results in the literature [2][3][4][5][6][7]. It is well known that the large hydrogen solubility in b.c.c.…”

“…As the result, Ti-Cr-V and TiCr-Mo ternary b.c.c. alloys were obtained by rapid quenching and their extremely high hydrogen absorption capacity, H > 3 wt.%, has been reported [3][4][5][6][7].…”

TiCrVMo alloys with high dissociation pressure for high-pressure MH tank

“…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.…”

“…It has two plateau pressures, where only the upper plateau pressure area can be used for reversible hydrogen storage in normal condition. Arashima et al have reported the alloy with 2.8 mass% of reversible hydrogen capacity [8]. However, as most of the previous works on these alloys have been aimed for low pressure (less than 1 MPa) system, dissociation pressures of these materials are often not enough to be applied for the high-pressure MH tank system.…”
