摘要: Abstract The hydriding and dehydriding kinetics of composite materials with the nominal composition Mg– x wt.% LaNi 5 ( =10, 20, 30) prepared by mechanical alloying components in a planetary mill an acceleration 12 g have been investigated. It has shown that addition improves absorption–desorption characteristics magnesium towards hydrogen, best achievements belonging to containing 30 . data obtained on changes occurring phase samples as result hydrogen cycling available information from literature used explain behaviour during hydriding. Comparison results composites same other methods shows ensures preparation favourable kinetic which are hydrided under softest possible conditions.
