Microstructural and corrosion characteristics of Quenched ...Jan 20, 2020 · In low carbon steel, there are 3 major forms of microstructural phases – namely, ferrite, pearlite, and martensite. Pitting corrosion preferentially occurs on ferrite phase and is reported to have corrosion activity in the order of ‘ferrite > martensite > pearlite’ . In a similar way, in dual-phase steels, the martensite regions are reported to show slower corrosion rates than ferrite regions.Cited by: 3Publish Year: 2020Author: Sooraj A.O. Nair, Radhakrishna G.
