| Abstract | ||||
| ABSTRACT High temperature fatigue bending properties of low carbon steel was studied. Tests were carried out on a constant speed of 50Hz (3000rpm) at 300°C and 500°C by decreasing stress amplitudes. The investigation was performed based on the stress-life (S-N) approach for high cycle fatigue regime, to establish the empirical equations for fatigue strength and endurance limit. The endurance limit for 300°C is 249.9MNm-2 with knee at 10.03 million cycles while for 500°C it is expected to occur on 171.0MNm-2 at 43.29 million cycles. For low carbon steel test at even higher temperature will experience further drastic drop in fatigue strength. | ||||
