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.
