Abstract
Examines the changes which occur in the powders used to prepare Fe-R-B permanent magnets upon heating. Exothermic reactions observed upon heating the powders; Correlation of differential scanning calorimetry with the magnetic properties of Fe-R-B powders; Reaction between chemisorbed oxygen and rare-earth metals to form bulk oxides.
