In the present study, effect of heat treatment on microstructure evolution and mechanical behaviour of C45 medium carbon steel was investigated. The samples were solution treated at 900 °C with a soaking time of 3 hrs and 1.5 hrs, tempered at 300 ºC and 500 ºC with a soaking time of 0.5 hrs. Hardness tests were performed for as-received, heat treated samples and the obtained hardness values were ranged from 198 to 290 BHN. Tensile tests were carried out at room temperature and 850 ºC at the strain rates of 1×10-2 s-1 and 1×10-4 s-1. Optical microscopy, SEM and XRD characterisation revealed the changes in the microstructure morphology and formation different phases depending upon the heat treatment temperature and soaking time.
