Abstract
Global warming and extreme climate problems caused by the intensive exploitation of fossil fuels have become increasingly serious. With the urgent global demand for clean energy, green hydrogen energy has become one of the important directions for future energy transformation due to its zero carbon emissions and wide source. However, embrittlement occurs in almost all metals when exposed to hydrogen, which greatly hinders the development of the hydrogen energy industry. Furthermore, the key application terminals of hydrogen energy are found in engineering equipment for aerospace, civil engineering, transportation and other fields. These equipments must endure long life with high reliability operation requirements. Therefore, accurately evaluating their Very High Cycle Fatigue (VHCF) characteristics in a hydrogen environment is the key for the future advancement of the hydrogen energy industry. In this article, the latest related research on VHCF failure behavior and hydrogen embrittlement mechanisms are briefly reviewed. At the same time, this work focuses on the impact of hydrogen on VHCF behavior, with the aim to provide some guidance for the research on VHCF characteristics and the design of metal equipment in hydrogen environment. Finally, this review summarizes the current higher-level challenges of VHCF research in hydrogen environments and provides some potential tools that may further address these challenges.
期刊介绍：
Engineering Failure Analysis publishes research papers describing the analysis of engineering failures and related studies.
Papers relating to the structure, properties and behaviour of engineering materials are encouraged, particularly those which also involve the detailed application of materials parameters to problems in engineering structures, components and design. In addition to the area of materials engineering, the interacting fields of mechanical, manufacturing, aeronautical, civil, chemical, corrosion and design engineering are considered relevant. Activity should be directed at analysing engineering failures and carrying out research to help reduce the incidences of failures and to extend the operating horizons of engineering materials.
Emphasis is placed on the mechanical properties of materials and their behaviour when influenced by structure, process and environment. Metallic, polymeric, ceramic and natural materials are all included and the application of these materials to real engineering situations should be emphasised. The use of a case-study based approach is also encouraged.
Engineering Failure Analysis provides essential reference material and critical feedback into the design process thereby contributing to the prevention of engineering failures in the future. All submissions will be subject to peer review from leading experts in the field.
