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

Failure Assessment for the High‐Strength Pipelines with Constant‐Depth Circumferential Surface Cracks [PDF]
Advances in Materials Science and Engineering, Volume 2018, Issue 1, 2018., 2018 In the oil and gas transportation system over long distance, application of high‐strength pipeline steels can efficiently reduce construction and operation cost by increasing operational pressure and reducing the pipe wall thickness. Failure assessment is an important issue in the design, construction, and maintenance of the pipelines.

Characterisation of the crack tip plastic zone in fatigue via synchrotron X‐ray diffraction
Fatigue &Fracture of Engineering Materials &Structures, Volume 45, Issue 7, Page 2086-2098, July 2022., 2022 Abstract This paper describes a new methodology for characterising the plastic zone ahead of a fatigue crack. This methodology is applied to a set of experimental data obtained by synchrotron X‐ray diffraction on a bainitic steel compact tension specimen.
