摘要：

Amorphous and nanocrystalline Mg-based alloys (Mg60Ni25)(100-x)Nd-x (x=2, 5, 10, 15) were prepared by melt-spinning. The microstructure of the as-quenched ribbons was characterized and the hydriding properties of these alloys were measured. The experiment results showed that the as-quenched amorphous (Mg60Ni25)(90)Nd-10 alloy displayed the best hydriding properties (hydriding kinetics and hydrogen absorption capacity), the maximum hydrogen capacity was of 4.2 wt.% H. The nanocrystalline (Mg60Ni25)(9)sNd(2) alloy showed slower hydriding kinetics and lower hydrogen absorption capacity compared to the other Mg-Ni-Nd amorphous alloys. It was conformed that the GFA becomes strong with the increase of neodymium for the as-quenched (Mg60Ni25)(100-x)Nd-x alloys, which leads to the higher H-capacity. (c) 2005 Elsevier B.V.
