## Attstraet-Dilatometric studies on the kinetics of Hydrogen Attack (HA) of carbon and 2: Cr-I MO steels have shown that the HA strain rates of these two steels differ by three to four orders of magnitude. A \* model based on constraint-free growth of methane bubles is used to show that the dilat
The material degradation process hydrogen attack has its origin in the dissolved hydrogen which reacts with the carbon of the steel to form methane inside grain boundary cavities. Hydrogen attack involves several interacting processes such as diffusion of carbon and of the metal atoms; dissolution o
