Hydrogen Storage Properties of V+ TiFe0.85Mn0.15 Multi- phase Alloys

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.
