In this study, influence of Al substitution on hydrogen storage properties of Ti₂CrV alloy has been investigated in detail. The alloys Ti_2–xCrVAl_x (x = 0.05, 0.1) were synthesized by arc melting method, and composition, type of crystal structure and hydrogen storage properties were evaluated. X-ray diffraction studies confirmed that all the alloys form single-phase bcc structures. Ti_1.95CrVAl_0.05 alloy is found to absorb a maximum of 3.9 wt% of hydrogen at room temperature and moderate hydrogen pressure. The plateau pressure of the studied alloys increases with an increase in Al concentration. The results confirm that among the studied alloys, Ti_1.95CrVAl_0.05 alloy shows the fastest hydrogen absorption kinetics and improved cyclic stability with a marginal decrease in total hydrogen absorption capacity compared to the parent alloy.

本研究详细研究了Al替代对Ti _{2 CrV合金储氢性能的影响。}采用电弧熔炼法合成了Ti _{2– x} CrVAl _x ( x = 0.05, 0.1)合金，并对其成分、晶体结构类型和储氢性能进行了评价。X 射线衍射研究证实所有合金均形成单相 bcc 结构。研究发现， Ti _1.95 CrVAl _0.05合金在室温和中等氢压下最多可吸收 3.9 wt% 的氢。研究合金的平台压力随着 Al 浓度的增加而增加。结果证实，在所研究的合金中，Ti _1.95 CrVAl _0.05合金表现出最快的吸氢动力学和改善的循环稳定性，与母体合金相比，总吸氢能力略有下降。
