Description

  • Content Description: The fatigue crack propagation of 2 1/4 Cr-1 Mo steel was examined in air over a wide range of experimental conditions. The fatigue crack growth rate was found to: generally increase monotonically with increasing temperature from 172/sup 0/ to 866/sup 0/K, except in the range where dynamic strain aging occurs, near 644/sup 0/K; increase with decreasing frequency at room temperatures above 783/sup 0/K - this frequency dependence was not observed below 783/sup 0/K; and increase with increases in mean stress. The results were evaluated, and a simple empirical model was developed to yield estimates of average and upper limit crack growth rates as a function of temperature, frequency, and effective stress intensity. However, the model is not applicable in the low region where threshold effects become important since insufficient data were available in that range.
