Analysis of Hydrogen Embrittlement on Aluminum Alloys for Vehicle-Mounted Hydrogen Storage Tanks: A Review

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