Microstructural evolution and the mechanical properties of various carbon steels were investigated with the variation deformation temperature to explore the optimum microstructure with excellent combination of strength and ductility. For this purpose, three carbon steels containing different carbon contents were deformed using Gleeble 3500 at temperatures including austenitic, austenitic/ferritic, austenitic/cementitic, ferritic/cementitic regions. The results showed that in the medium and high carbon steels, cementite particles became finer with decreasing deformation temperature resulting higher hardness but lower ductility. Further effort is needed to find out optimum microstructures with enhanced mechanical properties.
