Metallic Materials Evaluation in Hydrogen Environments Lab (Sungcheol Park)
Machine-translated · View original
A materials strength lab that studies the strength of metals used in hydrogen environments.
AboutAbout the lab
Studying the strength of metals exposed to hydrogen.
The lab studies how metallic materials exposed to hydrogen gas are changed by the effects of hydrogen.
Hydrogen embrittlement, in which hydrogen enters the interior of a material and reduces its strength and ductility, is an obstacle to the safe design and cost reduction of equipment that uses hydrogen.
The lab works on elucidating the mechanisms of hydrogen embrittlement, establishing criteria for selecting metallic materials used in hydrogen gas, and establishing strength design methods for hydrogen equipment.
On the lab's website, it is introduced under the name "Hydrogen Storage Systems Lab (Matsunaga Lab)".
Key terms
- hydrogen embrittlement
- A phenomenon in which hydrogen enters the interior of a material and reduces its strength and ductility.
