| Summary: | Title screen The paper studies the influence of hydrogenation duration on structural and phase transformations, deformation mechanisms and mechanical properties of metastable austenitic steel Fe-18Cr-9Ni-0.5Ti-0.08C (in wt %) processed under cold rolling. Plastic deformation under rolling produces a two-phase ([gamma]+[alpha]) grain/subgrain structure in the steel. A yield stress and an ultimate tensile strength are reduced, but the elongation, on the contrary, is increased for hydrogenated and cold-rolled specimens in comparison with values for samples rolled without preliminary hydrogenation. Alloying with hydrogen prior to rolling increases the volume fraction of [alpha]-phase and contributes to the appearance of [epsilon]-martensite in steel structure. This effect is enhanced with the increase in hydrogen saturation duration. Режим доступа: по договору с организацией-держателем ресурса |
