Abstract
The corrosion-resistant austenitic stainless steels have a prospect of practical use when producing the containers for hydrogen storage and transportation. Despite the high corrosive characteristics, the chromium-nickel steels have the propensity to hydrogen embrittlement. In particular, this effect is peculiar for steels with low stacking-fault energy, which have the tendency to strain-induced phase transformations. But hydrogen embrittlement is observed in stable steels as well. To determine the influence of hydrogen charging on mechanical properties and fracture mode of commercial stable austenitic Cr17Ni13Mo3 steel, the uniaxial static tensile tests have been conducted at room temperature using the hydrogen-charged (electrochemically saturated in the sulfuric acid aqua solution) specimens. The microstructure of the side surfaces and the fracture character were studied by scanning electron microscopy. The results of the mechanical tests, the microrelief of the side surfaces and fracture surfaces of hydrogen-charged specimens were compared with the results of the same tests for hydrogen-free specimens. Hydrogen-charging does not affect significantly the mechanical properties of steel under the study as well as the pattern of plastic flow. The values of yield offset, tensile strength at break, the elongation and the strain-hardening coefficient remain unchanged after the hydrogen charging. The retention of plastic properties under the hydrogen charging is caused by the presence of two competing processes. On the one hand, a hydrogen-saturated layer is developed on the side-surfaces of specimens after the electrochemical treatment, which leads to the brittle cracks formation on the surface (leads to the embrittlement). On the other hand, the hydrogen charging promotes the micro-localization of shear in one system, contributes to an increase in the planarity of the dislocation structure, and, as a consequence, raises the plasticity in the central part of the samples where the concentration of hydrogen is lower than on the side surfaces, and the hydrogen transfer is carried out by the crystal structure defects during the process of tension (leads to the plasticization).
