The effect of hydrogen on the fracture toughness of friction‐stir welded API 5L X70 pipeline steels

Fatigue &Fracture of Engineering Materials &Structures, Volume 45, Issue 10, Page 3009-3024, October 2022., 2022
Abstract The hydrogen embrittlement (HE) leads to severe steel degradation of mechanical properties. The hydrogen atoms diffuse into the steel and get positioned into reversible and irreversible trap sites. The pipe to transport oil and gas needs to be welded to construct long‐distance pipeline projects; thus, friction‐stir welding (FSW) has proven an ...
