In this work, the electrochemical polarisation behaviour of twinning induced plasticity (TWIP) steel (Fe-Mn-Al-Si) has been studied in three different environments viz., acidic, basic and chloride containing solutions, and compared with interstitial-free (IF) steel. The electrochemical polarisation results showed that TWIP steel exhibits lower corrosion resistance as compared to IF steel in all the three environments. However, the corrosion resistance of the TWIP steel in alkaline and chloride solutions were not as substantially higher as observed in acidic medium. The results were consistent with the post-corrosion SEM analysis. The plausible mechanisms are discussed in this paper.
