Materials and Corrosion, Volume 74, Issue 5, Page 724-733, May 2023., 2023 This paper reports the pitting corrosion resistance of four types of microstructures (water‐quenched martensite, tempered martensite, bainite and degenerate pearlite, and ferrite–pearlite) in AISI 1045 medium‐carbon steel. The pitting corrosion resistances of the microstructures in near‐neutral pH solutions containing chloride ions are ordered as ...

Materials and Corrosion, Volume 73, Issue 3, Page 326-345, March 2022., 2022 Steel armor wires in flexible pipes can be subject to corrosion and hydrogen embrittlement during operation. The failure mechanisms can be complex and a better understanding of the relationship between the microstructure and hydrogen uptake is necessary for understanding the complex failures.

Effect of Interlamellar Spacing on the Monotonic Behavior of C70 Pearlitic Steel [PDF]
Advanced Materials Research, 2014 The effect of interlamellar spacing on monotonic behavior of C70 pearlitic steel was investigated. Tensile tests under X-ray diffraction coupled with self-consistent model have been used to identify the role of interlamellar spacing on the ferrite plasticity parameters and residual stresses.

Crevice corrosion of U75V high-speed rail steel with varying crevice gap size by in-situ monitoring
Journal of Materials Research and Technology, 2022 Crevice corrosion of high-speed rail steel U75V was studied with varying gap size by using self-designed device. Increasing gap size inhibited exterior cathodic reduction reaction of oxygen, inducing decrease of potential difference between interior and ...
