Abstract

(ZrTi)V₂alloy was prepared by vacuum induction melting method and then annealed at 950 °C for a long time. The phase composition and hydrogen absorption property were investigated. Results show that (ZrTi)V₂ alloy is composed of C15 Laves phase, α-Zr phase, Zr₃V₃O phase and V-based solid solution phase. The α-Zr phase and V-based solid solution phase decrease after heat treatment. The experimental alloy is easy to be activated. The best activation effect can be obtained by the process of removing gas at 400 °C for 1 h and a hydrogenation cycle. The equilibrium pressure is 8.1×10^-14 Pa at room temperature extrapolated by Van't Hoff line.
