description: This work is aimed at studying the formation of the M/A component in the bainitic structures of low-carbon low-alloy pipe steels. In the course of the work, the influence of the chemical composition of steel and thermomechanical processing parameters on the formation of the M/A component, as well as the influence of the M/A component on the viscous properties of the steel, was found out. The HSSM program is used to calculate the mass average temperature along the length and cross section of the sheet duringrolling to simulate rolling simulation using physical mod-eling methods. The method of simulation of rolling on the Gleeble-3800 complex based on the specified temperature and deformation parameters has been developed. As a result of simulating rolling on the Gleeble-3800 complex, a structure similar to the structure obtained during rolling under production conditions on the 5000 Mill was obtained. The influence of the pause during intermittent cooling on the formation of the M/A phase and on the proportionof residual austenite in it, as well as the influence of the deformation temperature on the proportion of the M/A phase in the bainite structure according to the calculated rolling simulation mode, is studied of the M/A phase, is studied.
