合成了适用于混合储氢容器的钛锰基AB2型合金，并对其氢化性能进行了评价。在钛锰二元合金中加入第三元素V。本工作合成的合金主要由C14Laves相和bcc相组成。对于Ti0.5V0.5Mn合金，在7MPaH2气氛下，243K时吸氢量为1.8wt.%，243K放氢压力为0.2-0.4MPa.该合金的氢气容量在7 Mpa的氢气压力下并未饱和，当氢气压力达到35 Mpa时，合金的氢气容量似乎有所增加。
Ti–Mn-based AB2-type alloys which are suitable for a hybrid hydrogen storage vessel have been synthesized and evaluated hydrogenation properties. As the third element V was added to Ti–Mn binary alloys. All the alloys synthesized in this work mainly consist of the C14 Laves and BCC phase. In the case of Ti0.5V0.5Mn alloy, the amounts of hydrogen absorption was 1.8wt.% at 243K under the atmosphere of 7MPa H2, and the hydrogen desorption pressure was in the range of 0.2–0.4MPa at 243K. The hydrogen capacity of this alloy did not saturate under 7MPa H2and seems to increase with hydrogen pressure up to 35MPa that is estimated working pressure of the hybrid hydrogen storage vessel.
