Influence of rare earth metals on mechanisms of localised corrosion induced by inclusions in Zr-Ti deoxidised low alloy steel

•Rare earth influence on pitting in Zr-Ti deoxidised steel in marine environment was studied.•No galvanic couple formed between inclusion and Zr-Ti deoxidized steel before/after adding rare earth.•Pitting initiated by microcrevices/lattice distortion surround ZrO2-Ti2O3-Al2O3 inclusion.•Chemical dis...
