Hydrogen storage properties of TiFe_xCr_yMn_z alloy activated and absorbed under 1.5 MPa hydrogen pressure have been studied,and the heason which improved the activation properties by adding Cr and Mn has been discussed.

• 研究了TiFe_xCr_yMn_z系合金在1.；5MPa氢压下活化吸氢的贮氢特性；并对Cr；Mn改善活化性能的原因进行了讨论。 结果表明；加入Cr；Mn后形成的第二相具有较高的活性；可作为吸氢择优途径；TiFe_xCr_yMn_z系合金是有希望的低压贮氢合金系列。
