2022, International Journal of Hydrogen EnergyCitation Excerpt :For instance, quench and tempered (Q & T) martensite structures are good candidates for various structural applications. However, the ingress of hydrogen, even in parts per million (ppm) levels, from service environments, or during manufacturing, can significantly deteriorate the performance of these materials [4–6]. Additionally, the complex microstructure of these materials involving various H trap states such as dislocations, precipitates, different microstructural boundaries such as grain boundary (GB), packet boundary (PB) etc. increases the difficulties of modeling and prediction.
Engineering Challenges Associated With Hydrogen Embrittlement in Steels
2021, Encyclopedia of Materials: Metals and AlloysA fast fracture approach to assess hydrogen embrittlement (HE) susceptibility and mechanism(s) of high strength martensitic steels
2021, Corrosion ScienceCitation Excerpt :As can be observed from Fig. 5, the HE index for 4340L and 4340 is approximately twice than that of 4140. The NFS% in case of 4340 is the lowest while it is maximum for 4140, which can be attributed to the fact that 4340 has the highest strength (both yield and tensile) and hardness [1,16]. However, the Q & T steels 4340L and 4140 have similar hardnesses but significantly different NFS% values, suggesting that strength is not the only consideration in the determination of HE susceptibility in this case.
