Abstract
Corrosion pits preferentially initiate in the bainitic regions of Q420qNH steel against the simulated marine atmospheric environment, where a high initial dislocation density is present. This occurs in addition to the initiation sites associated with nonmetallic inclusions that exhibit significant lattice distortion. The formation of corrosion the corrosion-induced non elastic buckling exacerbates the cyclic softening effect and significantly reduces fatigue strength. At a strain amplitude of 0.4 %, the fatigue life decreases by 73.2 % after 60 days of pre-corrosion treatment. Layered segregation of Cr and Cu alloying elements could develop the formation of dense rust layer to inhibit further surface degradation.
期刊介绍：
Corrosion occurrence and its practical control encompass a vast array of scientific knowledge. Corrosion Science endeavors to serve as the conduit for the exchange of ideas, developments, and research across all facets of this field, encompassing both metallic and non-metallic corrosion. The scope of this international journal is broad and inclusive. Published papers span from highly theoretical inquiries to essentially practical applications, covering diverse areas such as high-temperature oxidation, passivity, anodic oxidation, biochemical corrosion, stress corrosion cracking, and corrosion control mechanisms and methodologies.
This journal publishes original papers and critical reviews across the spectrum of pure and applied corrosion, material degradation, and surface science and engineering. It serves as a crucial link connecting metallurgists, materials scientists, and researchers investigating corrosion and degradation phenomena. Join us in advancing knowledge and understanding in the vital field of corrosion science.
