Modifications in the Macroand Microstructure of Multiphase Low Carbon Steel Grades under the Impact of Formation-Thermal Treatment
In this paper we analyze the effect of rolling parameters on the nature of structural phase transitions and mechanical properties of steel. It is shown that an appropriate combination of temperature, the degree and rate of deformation, provides a fine-grained structure of austenite with a highly polygonal substructure. It is found that for low-carbon steel rational mode of cooling and coiling after rolling characterized by the following parameters.
