description: The subject of the graduate qualification work is Â«Comparative studies of the mechanical properties and structure of low-carbon low-alloy steel plateÂ». This work is devoted to the study of the relationship between the structure and mechanical properties over the thickness of rolled plates up to 100 mm from low-carbon low-alloy steel with a guaranteed yield strength of 420 MPa. The analysis of foreign and domestic materials has been carried out. Investigated the change in the mechanical properties and structure through the thickness of sheet products 25.50 and 100 mm. The influence of the quantitative parameters of the structural components on the impact work at temperatures of minus 60 and minus 80 Â° C is established, and the reasons for the decrease in cold resistance in thick-plate products are revealed. The result of the work is the proposed recommendations for testing the fabrication of the manufacture of sheet products 25-50 thick in industrial conditions.The work was carried out on the scientific and technical basis of the National Research Center "Kurchatov Institute" - Central Research Institute of KM "Prometey" within the framework of the ENI CBC project ID KS1054.
