“…In addition, the size of the crystal grains will significantly affect the HE of the material. As the crystal grain size decreases, the HE sensitivity of the material decreases [18,[75][76][77]. As the annealing temperature increased from 1073 to 1373 K, the average grain size increased from 6.4 to 79.8 µm [78].…”

“…However, due to the wide application of aluminum alloys, when hydrogen embrittlement causes the failure of aluminum alloys, catastrophic accidents can occur. In order to alleviate these conditions, hydrogen embrittlement must be paid enough attention [18]. It affects the service safety of aluminum alloys in the automotive, hydrogen energy, aerospace, petrochemicals, and other industrial fields [19].…”

High-pressure hydrogen tanks which are composed of an aluminum alloy liner and a carbon fiber wound layer are currently the most popular means to store hydrogen on vehicles. Nevertheless, the aluminum alloy is easily affected by high-pressure hydrogen, which leads to the appearance of hydrogen embrittlement (HE). Serious HE of hydrogen tank represents a huge dangers to the safety of vehicles and passengers. It is critical and timely to outline the mainstream approach and point out potential avenues for further investigation of HE. An analysis, including the mechanism (including hydrogen-enhanced local plasticity model, hydrogen-enhanced decohesion mechanism and hydrogen pressure theory), the detection (including slow strain rate test, linearly increasing stress test and so on) and methods for the prevention of HE on aluminum alloys of hydrogen vehicles (such as coating) are systematically presented in this work. Moreover, the entire experimental detection procedures for HE are expounded. Ultimately, the prevention measures are discussed in detail. It is believed that further prevention measures will rely on the integration of multiple prevention methods. Successfully solving this problem is of great significance to reduce the risk of failure of hydrogen storage tanks and improve the reliability of aluminum alloys for engineering applications in various industries including automotive and aerospace.

The presence of hydrogen severely affects the mechanical properties of semi‐manufactured and final steel products. Such presence is affected by different factors which show up throughout the whole manufacturing process and varies during the different stages according to both product features and various process parameters. This article presents an experimental methodology to assess the critical hydrogen concentration in as‐cast and hot‐rolled billets in medium carbon steels, which allows highlighting their robustness to hydrogen embrittlement. Such approach is based on a combination of hydrogen‐induced cracking and slow strain rate tensile tests, which are conducted on both as‐cast and hot‐rolled billets samples. The experiments highlight that the hydrogen presence is more critical on the as‐cast semi‐products than on the hot‐rolled billets, which show a higher robustness, as they can tolerate higher values of hydrogen content.
