Fatigue Behavior Investigation and Micro-Analysis of X80 High-Strain Linepipe

摘要：

　　Symmetrical push-pull low circle fatigue tests were carried out with conventional and high-strain X80 linepipe material respectively.Micro-analysis was performed for deformation mechanism as well.Results showed that high-strain X80 linepipe material exhibited a lower cyclic softening rate and a longer low-circle fatigue life than those of conventional X80 linepipe material.
