摘要：

The influence of ball milling an AB(2)-type Laves phase pre-allow with Mg2Ni was investigated from a structural and a morphological point of view. The influence of such a milling on the hydrogen uptake properties was also investigated. It was found out that magnesium did not enter the pre-alloy cell, at least for low energy millings. However, the magnesium did intimately nix with the pre-alloy. Regarding the weakest milling, significant improvement of hydrogen absorption capacity and kinetics were observed. Referring to previous work, this enhancement was attributed to the magnesium enrichment of the surface consequent to ball milling with Mg2Ni. (C) 1998 Elsevier Science S.A.
