Abstract
The anodic potentiodynamic polarization behavior of various grades of cold-worked (rolling and machining) austenitic stainless steels were studied. Deformed specimens were characterized by Electron backscattered diffraction (EBSD) and Fourier transform infrared spectroscopy (FTIR)-imaging. The FTIR-imaging was used to quantify chromium oxide (Cr2O3) spectra. It was observed, average area under Cr2O3 spectra was decreased with increase in cold -working. The certain regions in deformed microstructure showed higher value of area under Cr2O3 spectra, indicated stability of passivation film that needs to be explored. There was no microstructurally different between machined specimens.
