“…A Larson-Miller constant (C LM ) of 20 is appropriate for normalization by the LMP for the present alloy 5) , and this value was used here. The creep rupture strength of the Alloy 617 used in this study was higher than the literature values 9,10) in Fig. 2(a).…”

“…There are several studies of the creep rupture strength 9,10) and precipitation behavior of the secondary phases [11][12][13][14][15][16][17] at 700 C to 800 C, which is the temperature range for A-USC. However, there are few detailed studies on the creep deformation behavior and the evolution of the deformation microstructure.…”

“…Most of the crack initiation sites were found at the free surface through the intergranular cracking resulting from the oxidation of surface-connected precipitates, formed on the grain boundary during high temperature exposure time. These precipitates were formed due to the high temperature process and distributed along the grain boundary where cyclic strain is localized [15]. Some damage mechanisms induced by the slip band can also be found for the high strain range, resulting in transgranular cracking in the interior grain.…”

“…A trendline of the average tensile strength of the combined datasets was used for the extraction of data. Creep test data were extracted from five sources [1,17,18,19,20], the longest of which extends to 43,706 h. A total of 420 creep rupture data points were extracted; 386 have a rupture time less than 10,000 h and 354 have an applied stress less than yield strength.…”
