Abstract
Powdered Nd-Fe-B-type permanent magnets were heated at 200 degrees C f or times up to 32 days. The evolution of the Nd2Fe14B magnetic phase, followed by Fe-57 Mossbauer spectroscopy, evidenced the positive influ ence of both the hydrogen decrepitation process and Co, Nb and V addit ives on the corrosion resistance.
