Summary:Title screen
The effect of rolling combined with hydrogen charging on the structural and phase transformations and mechanical properties of metastable austenitic stainless steel Fe-18Cr-9Ni-0.5Ti-0.08C (in wt %) was investigated. Deformation of steel is accompanied by the refinement of the structure due to the accumulation of deformation defects and strain-induced [gamma]-[alpha]¢ transformation. Hydrogenation promotes the formation of [epsilon]-martensite and increases the volume fraction of [alpha]¢-phase in steel structure under rolling, as compared to the state after rolling without hydrogenation. Mechanical properties of austenitic steel increase under rolling as compared to the initial state, but preliminary hydrogen charging has no significant effect on their magnitudes. Hydrogen alloying before rolling increases specimen elongation compared to rolling without hydrogenation.
