description: This work is devoted to a comparative study of phase transformations in steel with a yield strength of 690 - 890 MPa after quenching or quenching from rolling heating and tempering. Tasks that were solved during the study:
1. Investigation of phase transformations in steel of various alloying after quenching and quenching with rolling heating.
2. Determination of mechanical properties after quenching and quenching with rolling heating.
3. Study of the structure of steel.
4. Recommendations for choosing technological schemes for manufacturing sheet metal.
The research material was steel of various alloying with a yield strength of 690 - 890 MPa after quenching or quenching from rolling heating and tempering, manufactured at PAO Â«Severstal'Â» or OOO Â«OMZ-Spetsstal'Â».
The work was carried out on the basis of the Research Center âKurchatov Instituteâ - Central Research Institute of CM âPrometeyâ, where a significant part of the actual material was collected: the results of dilatometric and structural studies, thermokinetic diagrams were constructed.
As a result, a study was conducted of the influence of chemical components and production technologies on phase transformations, the mechanical properties of sheet metal prototypes, and a study was conducted. Based on the studies conducted, recommendations were developed on the selection of technological schemes for manufacturing sheet metal.
