摘要	A Mg-30 wt.% Ti37.5V25Cr37.5 hydrogen storage composite was successfully synthesized by reactive mechanical milling of a mixture of magnesium and Ti37.5V25Cr37.5 powder in a hydrogen atmosphere. The structural evolution during milling and after hydrogen absorption/desorption cycling was analyzed using XRD. The absorption/desorption rates and storage capacity at different temperatures were evaluated. By analyzing the variation of the Avrami exponent, the hydrogenation mechanisms during milling process were also estimated. A large hydrogen storage capacity and excellent absorption/desorption kinetics were achieved in this composite. (C) 2003 Published by Elsevier B.V.
