Article

The physical processes occurring in the final period of rolling of low-carbon steel in ferrite range are studied. In order to investigate static softening in many-stage hot deformation the specimens are subjected to double hot compression at 700 – 800°C at deformation rate of 1 sec–1 with the help of a Gleeble-3500 machine. After attaining a true strain of 0.5 the deformation is stopped and a pause of from 1 to 100 sec is applied. The kinetics of the static softening in the ferrite range is described by the Avrami equation. The activation energy of the process is determined.
