Experimental observations of nucleation and crack growth paths of hydrogen-induced cracking in pipeline steel

Ehsan Entezari et al.

Summary: The microstructural features that promote hydrogen-induced cracking (HIC) in internal, middle, and external layers of pipeline steels were investigated. It was found that the formation and propagation of HIC are influenced by the segregation degree and inclusion contents, with HIC nucleating in cuboidal and spinal inclusions and propagating along ferrite/pearlite bands with high misorientations. The crack geometry does not solely control the occurrence of HIC.

An experimental and statistical study on the characteristics of non-metallic inclusions that serve as hydrogen-induced crack nucleation sites in pipeline steel

Ehsan Entezari et al.

Summary: This study investigates the spatial distribution parameters of non-metallic inclusions (NMIs) at hydrogen-induced cracking (HIC) nucleation sites in steel pipes. The findings show that cubical and spinal NMIs, characterized by high misfit strain and von Mises stress, are favored sites for HIC nucleation. Furthermore, the study reveals that the shape and sharpness of NMIs, rather than their size, determine their role as HIC nucleation sites.

Hydrogen-induced cracking and blistering in steels: A review

May L. Martin et al.

Summary: This paper presents a review of the current state of scientific understanding of Hydrogen-Induced Cracking (HIC), a corrosion phenomenon in low-to medium-strength steels driven by the precipitation of gaseous hydrogen molecules within cracks. HIC is typically observed in sour (H2S containing) environments and involves multiple steps including hydrogen uptake, diffusion, precipitation, and crack growth driven by hydrogen gas pressure. Despite decades of study, a full mechanistic understanding of HIC remains elusive, but the maturation of characterization techniques offers hope for future advancements.

Effect of post-processing heat treatment on hydrogen embrittlement susceptibility of API 5L X70 pipeline steel

Sandeep Yadav et al.

Summary: Three different heat treatments were applied on X70 pipeline steel to study the effect of hydrogen ingress on the degradation of mechanical properties. The results showed a reduction in elongation and toughness of all hydrogen-charged samples, as well as a strong correlation between hardness and hydrogen embrittlement susceptibility. The treatments that resulted in the formation of cementite precipitates within the ferritic matrix showed improved resistance to hydrogen embrittlement.

Summary: This review evaluates the basic requirements for producing steels designated for application in extreme cold polar regions. It focuses on construction steels and high strength pipeline steel grades used in sub-zero temperature applications. The role of mechanical properties, chemical composition, and microstructure in designing steels for cold regions is critical, as well as the synergy between low temperature and corrosive degradation.

Effect of Cold-Rolling on Hydrogen Diffusion and Trapping in X70 Pipeline Steel

Alen Thomas et al.

Summary: The study indicates that with an increase in grain misorientation, the permeability and effective diffusion coefficient of the steel decrease, while total and irreversible trapping sites increase. The changes in hydrogen diffusion intensity within the microstructure show that deformed grains are the easiest path for hydrogen diffusion.

Evolution of microstructure and texture in pipeline steels at different TMCP procedures with regard to hydrogen induced cracking

Reza Pourazizi et al.

Summary: SEM and EBSD techniques were used to evaluate hydrogen induced cracking susceptibility in API X70 pipeline steels produced by thermo-mechanical controlled process (TMCP) in laboratory scale. The observations showed no dominant texture in the specimens with randomly distributed grains. Different TMCP parameters and rolling processes generate different grain sizes, and a high cooling rate does not allow the grains to grow, affecting the resistance to hydrogen embrittlement.

Effect of hydrogen charging time on hydrogen blister and hydrogen-induced cracking of pure iron

Xinfeng Li et al.

Summary: The study found that pure iron exhibits hydrogen blister and hydrogen-induced cracking under different charging times. An increase in charging time leads to larger hydrogen blister and hydrogen-induced cracking, as well as a change in hydrogen damage morphology. Hydrogen-induced cracking primarily occurs along grain boundaries, with grain boundaries oriented-{100}//ND and {110}//ND showing the highest susceptibility to HIC.

EBSD Microstructural studies on quenched-tempered API 5L X65 pipeline steel

Enyinnaya G. Ohaeri et al.

Summary: Heat treatment is suggested to improve microstructural properties for steels. Different quenching rates in brine and oil led to variations in microstructures, affecting the hardness values obtained after heat treatment. The quenching and tempering approach relieved high stored energy and retained key properties for safe pipeline operation, with reduced risks of HIC in oil quenched pipeline steels.
