Abstract: The structure and mechanical properties of low-carbon steel 09G2S (13Mn6) in quenched condition and after tempering at different temperatures are studied. Stress–strain curves in conventional and true coordinates are analyzed to determine the plasticity parameters of samples at uniform and localized deformation stages for the steel in different structural and phase states and to assess the accumulation of defects at different scale levels. Characteristic zones of fracture surfaces (fibrous, radial and shear lips) and the morphology of secondary local cracks formed under sever plastic flow both in the neck of the tensile samples and in propagation of the main crack are described. It is shown that the highly plastic state formed in steel 09G2S after tempering at 650°C promotes the appearance of a radial zone in the fracture surface, where secondary local cracks nucleate and grow by a ductile mechanism.
