A Multi-Billion-Dollar Question – Researchers Are Closer to Understanding Hydrogen’s Great Challenge

Hydrogen traps can be introduced into the material microstructure to immobilize or trap absorbed hydrogen, limiting the amount of hydrogen participating in the embrittling process. This study finds that adding the chemical element molybdenum to steel reinforced with Ti-carbides markedly enhances its ability to trap hydrogen.
