Abstract
The results of oxygen absorption in temperatures ranging from 200 to 500 °C are reported for the phases Fe17R2, R=Pr and Sm. It was observed that the oxygen saturation limit is temperature dependent, being of 3 at/fu at 200 °C, 12.8 at/fu at 300 °C, 20.3 at/fu at 400 °C, and 28.5 at/fu at 500 °C. This implies that above 200 °C the phase is deeply altered by oxygen absorption. Samples with absorption at 200 °C were studied as prepared and heat treated at 500 °C/40 h. The results show that the heat-treated samples consist of Fe17R2, Fe, and R2O3. Metallographic examination, susceptibility, and Mössbauer spectroscopy data support the hypothesis that the as-prepared samples consist of a mixture of Fe17R2 and ordered interstitial Fe17R2Ox.
