Abstract Crack growth rates, measured during push-pull, high-strain fatigue of lightly-notched 0.5CrMoV turbine casing steel specimens at 550 °C, were determined in air, steam, and under vacuum. With a dwell at peak tension, propagation rates decrease in the order air, steam, vacuum, except at low strains where rates in steam are less than under vacuum. When the dwell occurs in the middle of the cycle at zero mean strain, i.e. , at a starting stress less than at peak strain, crack growth… CONTINUE READING
