Abstract: Hydrogen embrittlement (HE) remains a critical challenge in the reliability and safety of metallic components across a range of engineering applications, from aerospace to energy infrastructure. This review comprehensively explores the fundamental mechanisms underlying HE—including hydrogen-enhanced decohesion (HEDE), hydrogen-enhanced localized plasticity (HELP), and hydride-induced embrittlement—across various metal systems. Emphasis is placed on advanced characterization techniques such as thermal desorption spectroscopy, atom probe tomography, and in-situ mechanical testing, which provide multi-scale insights into hydrogen transport, trapping, and damage evolution. The study further evaluates key factors influencing HE susceptibility, including alloy composition, microstructural features, environmental conditions, and applied stress states. Mitigation strategies are systematically discussed, focusing on alloy design, microstructural engineering, surface treatments, and thermal processing. By integrating mechanistic understanding with practical prevention methods, this work provides a comprehensive framework for the design and maintenance of hydrogen-tolerant metallic materials in modern engineering systems.
