摘要：

The effects of stress ratio on fatigue crack growth thresholds and low and intermediate fatigue crack growth rates are examined on steels with ferrite-pearlite and tempered martensite microstructures, tested in air. The analysis of available experimental data shows that simple empirical relationships can be used to describe the stress ratio dependence of thresholds and fatigue crack growth rates. Results also indicate that thresholds decrease linearly with yield strength. © 1979.
