The study of the structure and mechanical properties of structural steels S355J2 and S460M has been carried out. It is shown that under the influence of the thermal cycle of welding, the mechanical properties of the metal change, namely, with an increase in the cooling rate of the metal W6 / 5, an increase in strength characteristics, and a decrease in the parameters of plasticity, and impact strength are observed. This behavior is due to changes in the structure of the metal, in particular, the formation of hardening structures. Investigation of the diffraction of the inverse electrons of structural steel S355 J2 has been shown to differentiate structures in the state of supply and after the action of the thermal cycle of welding, but more detailed conclusions require further research.5481 Product Description popup.authors Завдовєєв Анатолій Вікторович popup.nrat_date 2020-04-02 Close
