Abstract
The rotating bending fatigue tests were performed on the specimens of 0.21% carbon steel with various circumferential notches at elevated temperature. The effects of the test temperature, the test speed and the notch sharpness on the fatigue strength and the notch factor were studied from various angles. The data indicate that the fatigue strength of the smooth specimen takes the highest value at a temperature of about 300°C based on the bluebrittleness. As the notch becomes sharper, such an increase of strength at 300°C is gradually eliminated, and for the sharpest notch the highest fatigue strength is obtained at a temperature of 500°C. The notch factor also takes the highest value at 300°C, and at 500°C it reduces considerably. The effect of the test speed is more pronounced for the sharper notch. The notch factor is decreased considerably by lowering the test speed at 500°C.
