Hydrogen absorption in a Ti-6Al-4V alloy prepared by ball milling was investigated in view of the reversible storage of hydrogen in a solid state. The material characterization by X-ray and neutron diffractometry demonstrated the formation of a single a phase whose unit cell expanded during the hydrogen absorption. The maximum storage capacity of this alpha phase was 1.8 wt% H and no hydride formation was observed, The existence of such a particular supersaturated hexagonal phase was attributed to the strongly defective structure formed by the mechanical alloying process.
