Abstract This paper reports on a study to investigate the creation of a mixed microstructure consisting of proeutectoid ferrite, bainite, and austenite in a medium carbon high silicon steel. The microstructure was produced through the use of a continuous cooling process at a moderate cooling rate from the austenitizing temperature range to room temperature. The investigation also examined the influence of this microstructure on the mechanical properties of the material. Test results indicate that the developed steel has better mechanical properties compared to commercially available dual phase steels.
