description: The work was carried out at the REC "Research and Modeling of metallic materials", where the following were carried out: physical modeling of the steel structure using the Gleeble 3800 complex, metallographic study of the structure of the obtained samples using optical and electron microscopy methods. The paper considers the formation of the austenitic structure of E76XF rail steel in the process of heating for rolling, and in the process of subsequent multistage plastic deformation. The mechanisms and kinetics of recrystallization were also studied. As a result of the work: 1) equations describing the growth of austenitic grain in the process of heating for rolling were obtained; 2) it was found that the chosen method of modeling multistage plastic deformation allows us to obtain structures similar to those of real rails; 3) supposedly the recrystallization mechanism has been changed during the process of modeling multistage plastic deformation.
