Abstract
We study the effect of cathodic polarization with simultaneous action of biogenous hydrogen sulfide on the susceptibility of AB-2Sh and St3sp structural steels to hydrogen embrittlement in marine biological media of different activities. Uniform and concentrated components of the plastic deformation caused by stretching of smooth cylindrical specimens at the rate of ɛ=10−1 s−1 under hydrogen charging conditions are determined. We suggest a method for identification of processes occurring in the neck of a stretched specimen with respect to those that can take place near crack-type defects in submarine constructions.
