摘要:

研究了(100—x)％V x％ TiFe0．85Mn0．15(x＝50，60，70)(质量分数，下同)合金的储氢特性。讨论了添加TiFe0．85Mn0．15对钒基合金活化、吸放氢性能与组织结构的影响。研究表明，所有试验合金无需活化处理即可吸氢。在室温和4．0MPa下，40％V 60％TiFe0．85Mn0．15合金的有效氢容量达到207ml／g。

Abstract:

The hydrogen storage properties of(100-x)%V +x%TiFe 0.85 Mn 0.15 (x=50,60,70)alloy have been investigated.It is i ndicated that the activation behavior of V -based alloys can be improved markedly b y the addition of TiFe 0.85 Mn 0.15 .All of these alloys could absorb hydrogen without the activation tre atment.For the 40%V +60%TiFe 0.85 Mn 0.15 alloy,the valid hydrogen capacity r eaches 207ml /g at 293K and 4.0MPa.The influence of the addition of TiFe 0.85 Mn 0.15 on the hydrogen storage properties a nd phase structure of alloy has been discussed.
