Abstract

The fatigue-crack-growth behavior of two types of pipeline steels, Alloy B [Fe–0.05C–1.52Mn–0.12Si–0.092Nb, weight percent (wt%)] and Alloy C (Fe–0.04C–1.61Mn–0.14Si–0.096Nb, wt%), have been investigated. Compact-tension (CT) specimens have been tested at various frequencies (10, 1, and 0.1 Hz) and different R ratios (0.1 and 0.5, R = P_min/P_max where P_min is the minimum applied load, and P_max is the maximum applied load) in air. It is concluded that higher R ratios lead to faster crack-growth rates (FCGRs), while frequency does not have much influence on FCGRs. Moreover, Alloy B tends to have better fatigue resistance than Alloy C under various test conditions in air.
