ABSTRACT
This research paper examines the impact of post-review cooling on the fatigue resistance of medium carbon steel (AISI 1045 S45C) through the application of various heat treatments and quenching in water or oil at temperatures of 275 °C, 475 °C and 675 °C. It also compares the effects of the two quenching media on the mechanical properties and fatigue resistance of the steel. Fatigue tests were performed under steady stress conditions with a stress ratio of -1. The results of the experiments indicate that water quenching at a holding temperature of 275°C for one hour provides the greatest fatigue resistance for the steel. This is due to the formation of diluted martensite. Long fatigue cracks were accurately measured using a scanning electron microscope (SEM). Two models were selected to evaluate the fatigue life of AISI 1045 S45C medium carbon steel tempered and hardened at different cooling temperatures. The first model was selected from the crack growth rate equation (dE/dN), and the second from the stress intensity factor equation (ΔS).
