抄録

Amorphous Gd-Co alloys were prepared over a wide composition range from 45 to 70 at % Gd by melt-quenching. These alloys absorbed a large amount of hydrogen in the amorphous state below 423 K. The hydrogen absorption capacity for the amorphous alloys was lower than that for the corresponding crystalline alloys and it increased with increasing Gd content in the alloy. The number of hydrogen atom absorbed per one gadolinium atom was approximately two with regardless to the alloy composition. On the other hand, the Laves phase compound GdCo_2 was changed to an amorphous phase after reaction with hydrogen below about 700 K, among all of intermetallic compounds formed in Gd-Co system. This amorphous alloy did not show a pressure plateau in the pressure-composition isotherm, in the same manner as other melt-quenched amorphous alloys.
