Investigation of thermal aging effects on the tensile properties of Alloy 617 by in-situ synchrotron wide-angle X-ray scattering

Abstract: The nickel-base Alloy 617 has been considered as the lead candidate structural material for the intermediate heat exchanger (IHX) of the Very-High-Temperature Reactor (VHTR). In order to assess the long-term performance of Alloy 617, thermal aging experiments up to 10,000 hours in duration were performed at 1000°C. Subsequently, in-situ synchrotron wide-angle X-ray scattering (WAXS) tensile tests were carried out at ambient temperature. M 23 C 6 carbides were identified as the primary precipitates, while a sma… Show more

“…Using in situ synchrotron wide-angle X-ray scattering (WAXS), a series of microstructure evolution information related to both elastic and plastic deformation can be unveiled by interpreting the diffraction information collected from a strain specimen. In the past decade, in situ synchrotron tensile tests have been successfully applied to a series of different advanced structural materials [10][11][12][13][14][15][16][17].…”

“…The constitutive red copper model used the Johnson-Cook model, the equation of state used the Gruneisen Equation, and the parameters shown in Table 2. The constitutive model of explosives used the high explosive burn model, the equation of state used the JWL equation [18], and the parameters shown in Table 3. During linear charge-shaped cutting, the process of crushing the drug cover, forming and stretching the jet, and penetrating the composite board is a large deformation movement with multimaterial interaction.…”

“…The diffraction contrast imaging of transmission electron microscopy (TEM) is capable of revealing the number density and size distribution of nanoparticles, whereas the high-resolution transmission electron microscopy (HRTEM) can capture the crystal structure of nanoparticles along with their orientation relationship with the austenite matrix. Additionally, having extraordinary beam energy and intensity, synchrotron radiation is an ideal tool to characterize inclusion phases that have marginal volume fractions [16,17,18] such as oxygen-enriched nanoparticles. In fact, synchrotron-based techniques have already been successfully applied to the characterization of ODS steels in the past few years [9,19,20,21].…”
