Title: Magnetic Characterization Of Oxidized Fe-nd Alloys
Author: Sinnecker E.H.C.P.

Abstract: In this work results of oxidation experiments on Fe-Nd alloys are presented. Samples were prepared by melting the metals and Nd oxide, and by melting the metals, stabilizing the alloys through long heat treatments, and oxidizing them in low-oxygen partial pressures. Two mechanisms of oxidation are observed, one with precipitation of a fine Nd2O3 dispersion in the alloy matrix, with simultaneous displacement of the phase compositions to Fe-rich values. Eventually, pure Fe striae are formed. The second mechanism corresponds to the direct formation of a mixed oxide and Nd2O3.
