Abstract
We outline basic regularities of the processes running in “deformed-metal-hydrogen” systems characterized by the existence of close correlations between the motion of hydrogen in the metal and the accumulation of defects. We select the specific features of the methodological and methodical aspects of evaluation of the influence of hydrogen on the physicomechanical properties of materials explained by the unique properties of hydrogen, namely, its extremely high diffusive mobility in solids and active localization in structural defects. Within the framework of the continuum mechanics of damage, we pose and solve the problem of diffusive penetration of hydrogen through a metal under loads. Unlike the well-known McNabb model, the proposed mathematical description of the action of defects as hydrogen traps takes into account the effect of mechanical loading of the material. In the statement of the problem, we reflect the influence of defects on the behavior of the surface concentration of hydrogen in the process of saturation. The numerical results are compared with the experimental data obtained for the process of cathodic hydrogenation of deformed steel specimens in acid and neutral media. The accumulated analytic results satisfactorily describe the complex character of influence of the level of stresses on the hydrogen permeability of steels.
