1. The number of cycles to fracture in the low-endurance fatigue of steel in corrosive and hydrogen-charging media is determined mainly by the mechanical factor (loading parameters and physico-mechanical properties of the metal). Owing to the relativ

1. The effect of cathodic polarization upon the endurance of steel fatigued (in the plastic range) in neutral and acid electrolytes is represented by qualitatively similar curves. This is an indirect proof of the possibility of hydrogen embrittlement

Electrotransport of hydrogen in Fe, Ni, and Cu at 40–80° C was studied and the effective charges of hydrogen atoms were calculated. The direction of electrotransport of hydrogen in these metals is temperaturedependent. Since the concentration and

The migration of hydrogen in α-iron under the influence of an electric field was studied in a wide temperature interval. In every case hydrogen migrated toward the cathode. The transport charges are positive and decrease exponentially with rising te

1. Elastic strains activate hydrogen diffusion through a steel membrane. 2. Intense hydrogen charging leads to an increase in hydrogen collector size and to local plastic deformation of the metal in the vicinity of the collectors. The reduction in hy

Microscope examination was used to study the sites at which cathodic hydrogen diffusing through an armco-iron membrane emerged from the metal. Changes taking place at these sites and the formation of discontinuities in the metal structure during prot
