Creep Performance and Microstructure Evolution of IN617 at 950 °C for VHTR Applications
Volume 2: Nuclear Fuel and Material, Reactor Physics and Transport Theory, and Fuel Cycle Technology, 2022Abstract IN617 was considered the primary material candidate for the IHX in the VHTR. Researching microstructure evolution during high-temperature creep of IN617 helped understand its fracture laws and guide IHX operation under creep loading. Creep tests of IN617 were conducted under 19 MPa, 24 MPa, 27 MPa, and 38 MPa at 950 °C.

Electrolytic Al2O3/Y2O3 double-layer coating on IN617 superalloy
Surface and Coatings Technology, 2006Abstract In this study, IN-617 superalloy was coated with Al 2 O 3 /Y 2 O 3 double-layer films by electrolytic deposition in Al(NO 3 ) 3 and Y(NO 3 ) 3 aqueous solutions. Characterization of coated specimens was conducted by thermo-gravitational analysis (TGA), X-ray diffraction (XRD), scanning electron microscopy (SEM), aqueous corrosion tests in

The Effects of Dwell on the LCF Behavior of IN617
Journal of ASTM International, 2011Abstract Much has been studied on the individual effects of creep and fatigue on alloy life. However, not much is known of the combined effects of these two mechanisms. Therefore, a study was put into place to determine the effects of dwell on fatigue life and deformation mechanisms, for IN617, a solid-solution strengthened Ni-base alloy

Thermal Shock Testing and Analysis of IN617 and Super 304H Samples
Journal of Pressure Vessel Technology, 2007The DOE/OCDO sponsored Ultrasupercritical Steam Boiler Consortium is conducting thermal shock tests on austenitic and nickel-based materials to assess their use in thick-section boiler components. This paper describes the tests on CCA617 (a controlled chemistry version of IN617) and Super 304H thick-walled tubes.

This paper investigates the metallurgical behavior and mechanical properties of the P91 steel welds joint. The joint of heat-resistant P91 steel has been welded by the gas tungsten arc welding (GTAW) process using the dissimilar Inconel grade 617 filler. The P91 welds joints have been subjected to varying heat treatment regimes in the temperature range

Cumulative damage theory has been extended to develop a deterministic fatigue life prediction model for materials subjected to superimposed thermo-acousto-mechanical cycling. This loading profile is exhibited by particular external panels of reusable hypersonic cruise vehicles. Both creep and fatigue (LCF) test data have been acquired for two candidate

Internal Nitridation of Ni-Based Superalloy IN617 During Aging at 950 °C
Volume 2: Nuclear Fuel and Material, Reactor Physics and Transport Theory, and Fuel Cycle TechnologyAbstract Aging experiments were performed on Ni-based superalloy IN617 at 950 °C in air (containing 78.8 wt.% N2) for three different durations (50 h, 500 h, and 3000 h). Internal nitridation was found. The layered distribution structures of oxides, nitrides, and carbides were investigated.
