摘要：

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