摘要

A simple casting process has been applied to produce binary Mg-X (X=Ni, Cu or Al) in situ composites for hydrogen storage. Besides a major single phase of primary Mg, nanostructured eutectic networks of Mg-Mg_2Ni, Mg-Mg_2Cu and Mg-Mg_(17)Al_(15) were formed during solidification of Mg-Ni, Mg-Cu and Mg-Al alloys, respectively. Each intermetallic phase has different effects on the hydrogen sorption kinet?ics of the Mg alloys due to their different reactivities with hydrogen. In this study, the relationship between hydrogen migration and microstructure of the cast Mg alloys is investigated. The influence of hydrogenation/dehydrogenation cycling on the formation of porous structures is further discussed.
