AboutAbout the lab
Exploring the strength of metallic materials in hydrogen environments
The Hydrogen-Compatible Materials and Fracture Science Lab studies how hydrogen affects the strength of metallic materials.
Hydrogen plays an important role both as an energy carrier and as a chemical raw material, but it can also reduce the strength of metallic materials.
To ensure the safety of equipment that uses hydrogen, the lab conducts strength tests of metallic materials in hydrogen environments, based on mechanics of materials.
The lab was established through the cooperation of the Department of Mechanical Engineering and the International Institute for Carbon-Neutral Energy Research (WPI-I2CNER).
Key terms
- Hydrogen embrittlement
- A phenomenon in which the strength of a metallic material decreases under the influence of hydrogen.
- Mechanics of materials
- The academic field that deals with the strength and failure behavior of materials when force is applied to them. It is the academic foundation of this lab.
- Creep in high-temperature hydrogen
- A phenomenon in which deformation progresses over time when force is continuously applied to a metallic material in high-temperature hydrogen.
ResearchResearch themes
To ensure the safety of equipment that uses hydrogen, the lab aims to clarify how hydrogen affects the strength of metallic materials. Its main research themes are hydrogen embrittlement, research on suppressing hydrogen embrittlement by adding trace impurities to hydrogen, creep in high-temperature hydrogen, and hydrogen attack.

To ensure the safety of equipment that uses hydrogen, the lab investigates how hydrogen affects the strength of metallic materials. Based on mechanics of materials, it conducts strength tests of metallic materials in hydrogen environments.
*Illustrative imageAnalysis of how hydrogen enters metals
For hydrogen to enter a metallic material, hydrogen molecules must dissociate into hydrogen atoms. To understand and analyze this phenomenon, the lab incorporates quantum mechanical calculations of chemical reactions.
*Illustrative imageMaterials testing in high-temperature hydrogen
Technologies that use high-temperature hydrogen, such as high-temperature fuel cells, high-temperature hydrogen production, hydrogen engines, and hydrogen-based steelmaking, are under development. High-temperature hydrogen is an extremely aggressive environment for metallic materials, and the lab has installed materials testing machines for use in high-temperature hydrogen.
