Mechanisms of the oxidation of metals and alloys: Annual progress report for the period 1 July 1985 to 30 June 1986

Technical Report ·
OSTI ID:7225415
Areas of research conducted during this period were oxidation/sulfidation of pure chromium, Fe-25 wt % Cr, and Fe-25 wt % Cr-10 wt % Al alloys, segregation of sulfur to grain boundaries in oxide scales, oxidation of rapidly solidified (crystalline) Fe-Cr-Ni-Si alloys, and oxidation of Cr-Y and Co-Cr-Y alloys. Work carried out in this program has demonstrated the occurrence of grain boundary segregation of sulfur in chromia and alumina scales and of yttrium in chromia scales. It has also been demonstrated that the segregated species cause a change in the growth rates of the scales, and, in the case of yttrium segregation, a change in growth mechanism and an increase in scale adherence.
