Rates of fatigue crack propagation vs. range of stress intensity factor (Al<) curves for this alloy has been plotted. Axial - loads were used on 120 mm. wide CT (Compact Tension) specimens. These tests were made at different stress ratios R (ratio of the minimum stress to the maximum stress) ranging from 0.6 to 0.911 and at maximam stress levels ranging from 0.6 - 2.7 Ksi (4.1- 18.4 MN/nr2) to study the effects of stress ratio on fatigue crack growth. The results were compared for both thicknesses. Finally, the da/dN versus K data have been analysed and «best fit» straight lines for the graphs computed by the least square method.
