This paper examines the behavior of medium carbon steels subjected to a bainitic transformation. The compositional analysis was performed to ascertain the percentage of carbon in the as-received materials. The specimens were machined to a precise gauge length and exposed to various bainitic transformation temperatures. Fatigue test was also performed with the use of Avery Dennison and bending stress was obtained using the curve supplied with the machine. The medium carbon steel specimens were austenitized at 900°C and then transformed into bainite at 200, 300 and 400°C for one hour and also at 300°C for periods of 20, 40, 60, 80, 100, 120 and 140 minutes to obtain various bainitic transformation microstructures. The results from the machine were converted to Mega Pascal (MPa) and the values used to plot S-N curves and fatigue behavior for the specimens at various bainitic transformation temperatures at different times were established. It was discovered that bainitic transformed medium carbon steel showed improved fatigue behavior.
