Abstract: Data are presented from fatigue-crack growth tests conducted on Type 304 S.S. in inert environments at elevated temperatures which show that the thermal-activation noted in similar tests run in ...

Abstract: Linear-elastic fracture mechanics techniques were used to characterize the fatigue-crack propagation behavior of Incoloy 800 in an air environment over the temperature range 75 to 1200 deg F (24 ...

Abstract: The fatigue crack propagation (FCP) behavior of several ASTM A302-B and A508-2 steels was characterized in deaerated elevated temperature aqueous environment. FCP behavior was determined over the ...

Abstract: The Ramberg-Osgood strain-hardening exponents and coefficients are characterized for an unirradiated ASTM A302-B steel over a wide range of temperatures from −129 to 260°C. The strain-hardening ...

Abstract: Five different product forms (sheet, plate, bar, forging, and weldments) all taken from the same heat of Alloy 718 were tested at five different temperatures in each of two different heat-treated ...

Abstract: The extension of a hypothetical crack in a piping elbow under fatigue loadings at elevated temperature is estimated using the analysis techniques of linear-elastic fracture mechanics. The assumptions ...

Abstract: A Criterion to predict under what conditions EAC would initiate in cracks in a high-sulfur steel in contact with low-oxygen water was recently proposed by Wire and Li (1996). This EAC initiation ...

Abstract: The fatigue-crack growth behavior of annealed types 304 and 316 stainless steels is determined over a range of cyclic frequencies in an air environment at temperatures of 800°F (427°C), ...

Abstract: The elevated temperature fatigue-crack propagation response of Inconel 600 and Inconel 718 was characterized within a linear-elastic fracture mechanics framework in air and low-oxygen liquid sodium ...
