چکیده انگلیسی
Quenched Fe–C materials with up to 0.875 wt.% C were examined in 8.5 M NaOH at 100 °C to better understand the effect of carbon on caustic stress corrosion cracking (SCC) of plain steels. Carbon at contents up to about 0.23 wt.% C accelerated anodic dissolution of iron, whereas at high contents it hindered corrosion and promoted the formation of magnetite. It is suggested that carbon particles on the corroding surface form confined regions with an increased concentration of H+ and HFeO2−, thereby favouring the formation of Fe3O4. Intergranular SCC can be explained by preferred anodic dissolution of grain boundary material enriched in carbon.
