摘要：Constant Fatigue life analysis was done to predict the fatigue life of carbon steel alloy specimens with three different content of carbon (0.758%C, 0.539%C and 0.319%C) under effect of temperature. The fatigue experiments were performed at room temperature (RT) and 100°C with the frequency of 23.34 Hz on a cantilever rotating bending fatigue testing machine. Constant amplitude fatigue test results at room temperature were compared with the fatigue test results at high temperature. The results showed that the fatigue life and fatigue strength decrease at elevated temperature (100°C) as compared to room temperature. Carbon content also had a great effect on fatigue properties in which increasing carbon percentage led to improve the fatigue strength and life up to 0.539%C, but fatigue properties decreased when carbon content exceeded that value .
