“…[13,14] The most significant effect is the severe deterioration of the mechanical properties of high-strength steel, which is manifested as the remarkable loss of plasticity. Gong [15] studied the hydrogen embrittlement failure mechanism of advanced high-strength steel and found that hydrogen charging severely deteriorated the plasticity and toughness of high-strength steel, resulting in quasicleavage fracture failure at yield in a tensile test. Shibata [16] quantitatively analyzed the mechanical response of the hydrogen-induced fracture of quenched martensitic high-strength steel and indicated that the increase in diffusible hydrogen content in the steel promoted the stable and continuous growth of hydrogen-related macroscopic cracks.…”

AH36 marine steel processed through high heat-input welding is subjected to microstructural characterization, hydrogen permeation test, internal friction test, and slow strain rate tensile test to reveal its hydrogen diffusion and hydrogen embrittlement failure behaviors. Compared with the base metal, the coarsegrained heat-affected zone (CGHAZ) exhibits a significantly coarsened microstructure and decreased hydrogen trap density, resulting in a high hydrogen diffusion coefficient and short hydrogen permeation time. The presence of hydrogen yields a hydrogen-induced Snoek internal friction peak and promotes the movement of the Snoek-Kê-Köster internal friction peak to the lowtemperature region. In addition, B and Kê peaks, which are not found in the base metal, appear in the CGHAZ. With increasing hydrogen content, the plastic loss and brittle fracture of the AH36 marine steel become increasingly significant, and the hydrogen embrittlement sensitivity of the heat-affected zone increases compared with that of the base metal. The discontinuous yield phenomenon gradually disappears under slow strain rate tension owing to the weak pinning effect of the Cottrell atmosphere on mobile dislocations.

“…The second peak is the diffusion hydrogen captured by ML and DISL in the material. [31,32] According to the previous discussion concerning the relationship between martensite structure and GBs, it is considered that ML cannot be calculated in EBSD test results under such magnification times. Therefore, it is considered that ML is not included in the statistics of LAGB.…”

The application of ultrahigh‐strength martensitic steel in automotive key parts can achieve automotive lightweight. However, the hydrogen embrittlement sensitivity of ultrahigh‐strength martensitic steel is widely concerned by the industry. This article compares the microstructure and the hydrogen brittleness resistance of two 1500 MPa martensitic steels. The grain boundary, the grain size, the martensitic lath, and the precipitate phase in martensitic steel are analyzed by electron backscatter diffraction and transmission electron microscope. The hydrogen desorption curves of the two steels are measured by thermal desorption analysis, and the phenomenon of hydrogen trapping in the materials is analyzed. A U‐bend test is used to compare the hydrogen embrittlement of these two samples. The results demonstrate that the thickness of the martensitic lath and the dislocation are directly related to the diffuse hydrogen concentration in the material. In addition, the Cu‐rich nanoparticles show a better hydrogen trapping effect, which is beneficial in improving the hydrogen embrittlement resistance of the material.

“…10,11 The embrittlement effect often occurs in an unpredictable manner, as the ingress of the ubiquitous H into a material is difficult to avoid and a H concentration of only a few parts per million by weight is often sufficient to cause catastrophic failure. 5,[12][13][14][15][16] Thus, HE can basically threaten any industrial and societal applications in a H economy that aim to use highperformance alloys to make structural components.…”

Hydrogen embrittlement (HE) is characterized by the sudden loss of a material's mechanical property due to the premature failure induced by the ingress of H atoms and various H‐materials interactions. This phenomenon threatens almost all the metallic materials that brings an abrupt halt to some of the pending infrastructures needed for a H economy. The development of microstructure design strategies to mitigate HE is challenging, as the fundamental mechanisms for HE process are still not well understood. Nevertheless, some progresses in this field have been made in recent years. Here, we provide an overview on established microstructural approaches to mitigate HE in metallic materials. These methods include second‐phase trapping, grain refinement, grain boundary engineering, solute segregation and heterogeneity, and surface treatment. Their effectiveness and materials applicability are compared. The operating mechanisms, advantages, and limitations of these approaches are also discussed to guide their future development and successful industrial application.
