Insight into TiN inclusion induced pit corrosion of interstitial free steel exposed to aerated NaCl solution

open access: yesJournal of Materials Research and Technology, 2021
The mechanism of step-like corrosion pit induced by TiN inclusion in Ti-stabilized interstitial free steel was systematically investigated. There was neither micro-crevice nor local stress in the steel matrix adjacent to the TiN inclusion, but a ...
