Fig. 9: Typical morphology, properties and corrosion performance of TiN inclusions in interstitial free steel.
From: A critical review of the recent advances in inclusion-triggered localized corrosion in steel

a SEM images of TiN inclusions in interstitial free steel. b Morphology and potential results of line profile in the same region from a. c, d Ex-situ SEM morphological observation of corrosion pit induced by TiN inclusions with time in 0.1 M NaCl solution after removal of corrosion product: c 7 min and d 15 min. Corresponding three-dimensional images and cross-section of the corrosion pit are illustrated on the right87.
