Abstract
The mechanism of oxidation at 1000°C of Fe-Cr alloys has been investigated. The samples were oxidized in two stages: first in an atmosphere of 16 O and subsequently in 16 O. Prior to each stage the samples had been marked with platinum wire markers. The concentration of 18 O in the scale was determined by means of two nuclear reactions: 18 O(α,n) 21 Ne, and 18 O(p,n) 18 F independently. The results show that the dissociative mechanism of scale growth on Fe-Cr alloys is similar to that found earlier for Cu-Zn type alloys for which measurements were made using the radioactive sulfur isotope,35 S.
