Essay

Current thesis provides the experimental investigations devoted on the development of the formation of the structure and substructure of the microalloyed low-carbon structural steels in dependence on the parameters of the austenite decomposition. TEM allowed the highly precise investigations of low-carbon structural steels after the isothermal decomposition in the temperature range from 200°С to 700°С. The redistribution of the alloyed elements in the different austenite decomposition products have been studied qualitatively and quantitatively. The influence of this redistribution on the ferrite-pearlite bands geometry and location as well as on the fracture properties of the material has been shown. The recommendations to the production procedure of the thick steel plates with the elevated mechanical properties have been proposed.
