Research on the effect of hydrogen on the low-cycle fatigue property of the heat-affected zone of the X80 welded pipe

Lei Tang, Yingdun Wang, Bochen Gao, Jitong Sha et al.

Short summary

Hydrogen exposure reduces the low-cycle fatigue life of X80 welded pipe heat-affected zones (HAZ), with coarse-grain HAZ experiencing a 78% decrease in fatigue life, while fine-grain HAZ shows a 43% decrease.
