摘要: Abstract Mg-5wt%Ni-2.5wt%Fe-2.5wt%V (named Mg-5Ni-2.5Fe-2.5V) powder was prepared by reactive mechanical grinding using a planetary ball mill. The activation process, the changes in phase and microstructure with hydriding-dehydriding cycling, variations hydriding dehydriding rates temperature were investigated. rate-controlling step for reaction of Mg-5Ni-2.5Fe-2.5V analyzed spherical moving boundary model. As increased from 473 K through 623 K, initial hydrogen absorption rate under 12 bar H 2 decreased, while desorption 1.0 bar increased.
