EXPERIMENTAL STUDY OF THE CHANGE OF THE STRENGTHENING ZONE ON CORRODED STEEL SPECIMENS

The presence of the strengthening zone in the stress-strain diagram is explained by the fact that the sliding of each individual crystal in the steel cannot grow indefinitely. Corrosion have a negative influence on the steel element. We have made an experiment to determine if there is a change in the zone of strengthening. For this purpose, we used classic S355JR structural steel subjected to electrochemical corrosion. We split the strengthening zone into 8 equal parts and took the values from the diagram. We processed them using the stochastic method. We have come to the conclusion that corrosion indicates a significant impact on this area by making the structure of the polycrystalline steel grid is transforming
