Abstract
The desorption of hydrogen from the alloys Nd 11.8Fe 82.4B 5.8 (formula unit Nd 2Fe 14B), Nd 15.5Fe 77.5B 7, Nd 12.5Dy 3Fe 74.5V 3B 7 and Nd 12.5Dy 3Fe 69.5Co 5V 3B 7 (the numbers are atomic percentages of the elements) and from 95% pure neodymium has been investigated by mass spectroscopy. These studies indicated that the desorption of hydrogen from the multiphase alloys is a three-stage process: (1) desorption from the matrix Nd 2Fe 14B, (2) partial desorption from the neodymium-rich material and (3) complete desorption from neodymium-rich material. The desorption behaviour of the cobaltcontaining alloy indicated a change in the character of the grain boundary phases in the alloy.
