dc.description.abstractAdditively manufactured AISI 316 L stainless steel samples were heat treated at temperatures from 400 ◦C to 1100 ◦C, and the corrosion behavior in chloride environments was electrochemically studied. Heat treatments at 400 ◦C and 650 ◦C increased the grain size and the treatment at 1100 ◦C formed MnCr2O4 inclusions. Also, these postprocessing techniques reduce the hardness and increased the porosity. Heat treatment at 400 ◦C increased the polarization resistance and maintained the pitting corrosion mechanisms of the additively manufactured samples. Heat treatments at higher temperatures reduced the polarization resistance but changed the corrosion resistance mechanisms.es
