Description
Hydrogen Embrittlement (HE), a subset of Environment-Assisted Cracking, has been recognized as a predominant failure mechanism in high-strength steels (HSS), leading to substantial socio-economic losses globally each year. High-strength steels exhibit greater susceptibility to HE compared to low-carbon steels. The initiation and propagation of HE deterioration result from the synergistic interaction of a susceptible material, applied stress, and a hydrogen-rich environment. The structural integrity of high-strength steel (HSS) is affected by hydrogen embrittlement (HE), which reduces ductility and other mechanical properties such as tensile strength, toughness, and fatigue strength. This facilitates brittle fracture crack nucleation and propagation phenomena caused by the diffusion of hydrogen into the metal. Failures have been observed despite numerous studies on this topic. Additionally, various mechanisms have been proposed over the years, but a general consensus has not yet been reached. Therefore, this paper presents recent research findings on the hydrogen embrittlement (HE) of high-strength steel (HSS). The study primarily focuses on the structural integrity of HSS. It provides an overview of the development of HE failure mechanisms and their effects on mechanical properties to provide a deeper understanding to facilitate the industrial applications of HSS. Additionally, the paper identifies existing research gaps and offers recommendations for future studies.
