ABSTRACT

The anodic potentiodynamic polarization behaviors of austenitic stainless steels, with varying Cu (copper) and/or Mo (molybdenum) additions,  were explored after plane strain compression. Though all the alloys showed developments in deformed microstructures, the presence of Cu + Mo did not result in strain induced marten site formation (SIMF). However, the presence of Cu + Mo revealed the highest degradation in corrosion performance. A combination of micro texture measurements and fourier transform infrared spectroscopy (FTIR)-imaging revealed that the presence of SIMF promoted post-passivation stability or retention of a protective Cr2O3 film.
