Abstract

This study dealt with characterizing oxide passive films in austenitic stainless steels with different chemical compositions. Stacking fault energy was estimated, and thermal conductivity at different temperatures (298, 673, 873 and 1073 K) were calculated. Steels specimens were plane strain compressed and subjected to anodic potentiodynamic polarization scan in a different deaerated testing environment. The deformed specimens were characterized using electron backscattered diffraction system and Fourier transform infrared spectroscopy (FTIR)-imaging. The Cr2O3 peak from FTIR-imaging was captured, and area of the peak was calculated after anodic potentiodynamic polarization scan. The intensity of Cr2O3 peak was related to deformed microstructural features.
