The present study has been undertaken in order to examine the kinetics of the isothermal transformation of the austenitic region at temperature range of 350-420 degrees centigrade in low carbon silicon manganese steel after annealing in two-phase region (A1-A2). Carefully designed control-cooling and isothermal bainite transformation allows to obtain a multiphase steel containing retained austenite (8-12%) susceptible to transformation - induced plasticity (TRIP effect). Mechanical properties and microstructural studies of steel after various stages of isothermal transformation were performed.
