The effect of 0.6-5 at.% Al on the structure and hydrogen storage properties of V30Ti35Cr25Fe10 hydrogen storage alloy was investigated by XRD and PCT measurement. It was found by XRD analysis and Reitveld method that all Al-containing alloys are single phases with BCC structures; and with the addition of Al content from 0.6 to 5 at.%; the lattice parameters of the alloys become larger; the hydrogen absorption and desorption capacities decrease; the desorption plateau pressures increase; but no evident effect is found when the content of Al is no more than l at.%. The formation of γ phase is inhibited by the addition of Al; and nearly no γ phase is formed when Al content reaches 5 at.%. © 2006 Elsevier B.V. All rights reserved;
