Abstract

A mixture with a composition $Mg_2Ni$ is mechanically alloyed. Its hydriding and dehydriding properties are compared with those of the intermetallic compound $Mg_2Ni$ prepared by partial melting and sintering. The principal effects of mechanical alloying in a planetary mill and hydriding-dehydriding cycling are considered the enlargement in the specific surface area and the augmentation in the density of defects.
