Problems of Hydrogen Degradation of Metals

We present a new scientific trend concerned with the behavior of materials interacting with hydrogen, namely, hydrogen-containing materials science. Most of the attention is concentrated on hydrogen degradation of structural materials, which is a major aspect of this trend, and the types of hydrogen degradation are considered. The most important factors predetermining the processes observed are the tendency of hydrogen to localization in the metal and a decrease in the binding forces between atoms of metal. Tasks aimed at solving the problems of hydrogen degradation of metals are formulated.
