121877 - Recent Advances in the Study of Hydrogen Embrittlement in Ferritic Steels 

Within the realm of sustainable alternatives, hydrogen is regarded as a prospective future fuel by the scientific community. Hence, the development of safe and economically efficient hydrogen storage and transportation methods is essentially required.¹ The interaction of hydrogen with structural materials is one of the major obstacles in the development of these storage and transportation techniques. In most cases, interstitial atoms determine the mechanical properties of structural materials. Hydrogen is a common interstitial element, which generally degrades the fracture behavior and leads to premature or catastrophic failure in a variety of materials, known as hydrogen embrittlement.² This implies that hydrogen embrittlement can occur in most structural materials, including ferritic steels, an important class of materials.³

The process behind the hydrogen embrittlement of ferritic steels remains largely unclear despite significant research efforts aimed at understanding these mechanisms and creating potential mitigating measures.⁴ New developments in multi-scale modeling, and experimental instruments are beginning to shed light on the embrittlement process of ferritic steels.⁵ This report represents a subset of the most recent advancements, highlighting the ways in which novel techniques have enhanced our comprehension of the relationships between structure, properties, and performance of ferritic steels under mechanical loading in a hydrogen environment. Next, a thorough analysis of the different embrittlement mechanisms will be presented in order to investigate the performance of steels in hydrogen. Furthermore, an insight into contemporary methodologies and novel mitigation strategies employed in the design of hydrogen embrittlement-resistant steels will be presented.
