Abstract

Hydrogen absorbing and desorbing rates are measured for melt-spun Nd-Fe(or Co)-B amorphous alloys containing 5-30% Nd and 0-15% B. The hydrogen capacity changes with the Nd concentration roughly as ∼3.0 H/Nd, although it is also affected by the B concentration. In alloys where Nd concentration does not exceed 20%, most of the absorbed hydrogen is desorbed from the amorphous phase. X-ray structure analysis shows that the short-range order of the amorphous alloy is maintained before and after the hydrogenation.
