We analyze the results of investigations of the interaction of hydrogen with metals under the conditions of their deformation. We formulate the conclusions about the fracture and strength of structural materials made on the basis of the experimental data accumulated at the Karpenko Physicomechanical Institute of National Academy of Sciences of Ukraine for the last 70 years (since 1951). Main attention is given to the dual character of the influence of hydrogen on the deformation of metals. Indeed, at low concentrations, it promotes their plasticization, whereas at high concentration, it caused their embrittlement. The indicated features of the interaction of hydrogen with metals form a basis for the prediction of the durability of metal structure in hydrogen-containing media and for development of products with high physicomechanical characteristics.
