Abstract
The long-term exposure of X80 pipeline steel to hydrogen presents significant challenges. In this study, we establish a quantitative relationship between hydrogen content and the low-cycle fatigue (LCF) lifetime of X80 pipeline steel by integrating fatigue experiments, microstructure characterization, molecular dynamics simulations, and a damage plastic strain energy model. Additionally, we investigate the microscale mechanisms governing microstructure and energy evolution in pipeline steel under LCF loading. These findings contribute to a deeper understanding of the failure mechanisms and provide valuable insights for assessing the safety of hydrogen service in pipelines.
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.
