Special Issue of ISIJ International on “Innovative evaluation techniques for hydrogen entry and hydrogen trapping” (Submission deadline: 30th April, 2026)
In order to reduce embrittlement and delayed fracture caused by hydrogen that penetrates into metallic materials such as steel due to environmental interactions including atmospheric corrosion in various environments, research on the mechanism of hydrogen entry reaction in materials has been actively conducted in parallel with the development of materials with microstructures that are resistant to hydrogen embrittlement. While some issues have been solved, there are still many unresolved issues to be investigated. Among the representative issues are (1) standardization of hydrogen charging methods for hydrogen embrittlement tests and (2) development of hydrogen permeation distribution evaluation methods that will lead to the identification of the origin of hydrogen embrittlement. To solve these problems, understanding the amount and distribution of hydrogen that enters and is trapped in materials through corrosion and electrochemical reactions is an important analytical element. In addition, it is necessary to verify that hydrogen embrittlement occurs when the amount of hydrogen that enters the material exceeds the critical hydrogen capture level by applying the results to the hydrogen penetration and capture phenomena in practical materials, and to summarize the previous related knowledge and mathematical modeling of the hydrogen entry and trapping phenomena to enable simulation. In order to select and use appropriate hydrogen embrittlement test conditions that suit the actual service conditions of the material, the construction of a hydrogen penetration and trapping evaluation technique that enables detailed understanding of the hydrogen that enters and/or is trapped in the material as a result of corrosion or electrochemical reactions, as well as the amount, rate, and location distribution of the hydrogen, is being considered.
This special issue aims to strengthen research activities in the field of evaluation techniques for hydrogen entry and hydrogen trapping in high strength steels as well as various other metallic materials, and to analyze the reaction mechanisms based on these techniques. In addition to the papers from the general public, this special issue also includes the papers from the international organized session “Innovative evaluation techniques for hydrogen entry and hydrogen trapping-IV” at the 188th Autumn Meeting of the Iron and Steel Institute of Japan (held on September 18th, 2024 in Toyonaka Campus, Osaka University).
1. Scope
The main focus will be on the latest research and reviews related to 1) standardization of hydrogen charging methods for hydrogen embrittlement test methods for practical steel materials and 2) development of hydrogen entry distribution evaluation methods that can lead to the identification of the origin of hydrogen embrittlement. Thus, related topics include corrosion and electrochemical reactions, hydrogen entry, hydrogen trapping, hydrogen embrittlement, mathematical modeling, and simulation.
