■概　要

Ball milled Mg–Co alloys with body-centered cubic structure (BCC) may absorb hydrogen at 258 K with a hydrogen capacity around 3 mass%. The phase and morphology evolution process of Mg₅₀Co₅₀ alloys ball milled for 0.5 h–400 h was studied by X-ray diffraction and scanning electron microscope. The formation mechanism of the Mg₅₀Co₅₀ alloys was clarified. Mg₅₀Co₅₀ alloys ball milled for various durations were found to present different hydrogen storage properties which could result from the phase and morphology difference in these samples.
