“…H induces a localized stress concentration at the twin–twin boundary intersections. These sites are crack initiation sources and expedite fracture [ 62 , 63 ]. Therefore, with an increase in the fraction of mechanical twins in the thick strut, T1.4, the number of crack initiation sites increases.…”

In the present study, the hydrogen embrittlement (HE) susceptibility of an additively manufactured (AM) 316L stainless steel (SS) was investigated. The materials were fabricated in the form of a lattice auxetic structure with three different strut thicknesses, 0.6, 1, and 1.4 mm, by the laser powder bed fusion technique at a volumetric energy of 70 J·mm−3. The effect of H charging on the strength and ductility of the lattice structures was evaluated by conducting tensile testing of the H-charged specimens at a slow strain rate of 4 × 10−5 s−1. Hydrogen was introduced to the specimens via electrochemical charging in an NaOH aqueous solution for 24 h at 80 °C before the tensile testing. The microstructure evolution of the H-charged materials was studied using the electron backscattered diffraction (EBSD) technique. The study revealed that the auxetic structures of the AM 316L-SS exhibited a slight reduction in mechanical properties after H charging. The tensile strength was slightly decreased regardless of the thickness. However, the ductility was significantly reduced with increasing thickness. For instance, the strength and uniform elongation of the auxetic structure of the 0.6 mm thick strut were 340 MPa and 17.4% before H charging, and 320 MPa and 16.7% after H charging, respectively. The corresponding values of the counterpart’s 1.4 mm thick strut were 550 MPa and 29% before H charging, and 523 MPa and 23.9% after H charging, respectively. The fractography of the fracture surfaces showed the impact of H charging, as cleavage fracture was a striking feature in H-charged materials. Furthermore, the mechanical twins were enhanced during tensile straining of the H-charged high-thickness material.

“…33 Different types of coatings (e.g., metallic, polymeric, and ceramic) have been developed in this regard, which has been thoroughly reviewed recently. 33 However, such approach might encounter durability problems in harsh (like abrasive and corrosive) environments. 34 In some cases, H might even be generated and be absorbed when a coating corrode, due to the electrochemical reaction between the exposed areas of the metal substrate and the coating material.…”

“…Despite the existence of debates among the above mechanisms and the boundary conditions for their prevalence, a variety of methods have been developed to mitigate H embrittlement in metallic materials. The perhaps most common engineering solution is to suppress H ingress by applying protective barriers or coatings that have a low H permeability or diffusivity 33 . Different types of coatings (e.g., metallic, polymeric, and ceramic) have been developed in this regard, which has been thoroughly reviewed recently 33 .…”

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.

“…However, there is a considerable imbalance between supply and demand due to the great dependence on the availability of renewable energy sources, such as solar and wind energy, since they are season-dependent. Therefore, converting the excess energy into an energy carrier, such as hydrogen, and storing the hydrogen until needed, is a workable solution to the challenges affecting renewable methods and the energy gap. , Hydrogen is now an attractive energy storage option, to be the future form of leading energy and versatile industrial raw material, due to its high specific energy capacity of 120–142 MJ/kg, its availability, and its clean combustion product (only water vapor). , However, in comparison to other available energy sources (e.g., traditional fossil fuels), the physical and chemical characteristics of hydrogen, such as its low volumetric and energy densities at room temperature, high-pressure vessels (operated at 700 bar), liquid conditions (cryogenic), and hydrogen embrittlement, have made it extremely difficult to be economically and safely stored and transferred for mass application in recent years. − …”
