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。The hydrogen storage properties of (100-x)% V + x% TiFe0.85Mn0.15(x =50, 60, 70) alloy have been investigated. It is indicated that the activation behavior of V - based alloys can be improved markedly by the addition of TiFe0.85Mn0.15. All of these alloys could absorb hydrogen without the activation treatment. For the 40% V + 60% TiFe0.85Mn0.15 alloy, the valid hydrogen capacity reaches 207 ml/g at 293 K and 4.0 MPa. The influence of the addition of TiFe0.85Mn0.15 on the hydrogen storage properties and phase structure of alloy has been discussed.
