Hydrogen embrittlement (HE) of steels continues to be an area of interest for the oil and gas (O&G) industry. Despite significant research, the mechanism(s) governing failure in the presence of hydrogen remains to be fully resolved. This article attempts to highlight key features of one recently proposed mechanism, with emphasis on the evolution of hydrogen induced damage leading to failure. It...
The atomic-scale study of solid-solid interfaces in complex multi-phase multicomponent systems is a challenging but important endeavor. This article highlights the coupling of recently developed advanced characterization techniques, such as high resolution scanning transmission electron microscopy, carried out in an aberration-corrected microscope, and atom probe tomography, to address the structural...
