Abstract:The high temperature oxidation behavior of an Fe-16Cr binary alloy, oxidized under different compressive stresses in air at 900 degrees C, was investigated. Surface and cross-sectional micrographs, observed by scanning electron microscopy, indicated that the resulting morphology of the thermally grown oxide scale depended on the compressive stress. Results showed that oxide scales were infact below 5 MPa stress after 10 h of oxidation. Delamination developed at the outer/inner oxide scale interface in the case of compressive stress above 5 MPa. Growth kinetics measurements revealed that the rate of oxide-scale growth increased by the compressive stress.
