The results show that the alloys is composed of BCC phase and C14 Laves phase.

研究表明：合金由C14Laves相和BCC相构成；

C14 Laves phase also works as an electrochemical catalyst for the V base solid solution phase, which enhances the use of V base solid solution phase to make electrochemical properties of Ti-V base multiphase hydrogen storage electrode alloys preferable.

因此，该合金中，Laves相既是吸氢相又是催化相，提高合金中V基固溶体相的利用率，从而使Ti-V基贮氢合金具有较好的综合电化学性能。
