On the behavior of hydrogen in metal alloys

The article considers the interaction of hydrogen with crystal structure defects in metals and alloys. The classification of hydrogen traps in terms of their energy levels is given. Various types of interactions of hydrogen traps are considered, depending on their binding energy. The effect of hydrogen traps on the diffusion coefficient of hydrogen in steel has been studied. It is shown that the presence of high-energy hydrogen traps in metals leads to a decrease in the dif-fusion mobility of hydrogen, which is thereby excluded from the embrittlement process.
