| Abstract Scope |
Inconel 617 (IN617) is a nickel-based superalloy that has been recognized as a promising candidate for nuclear applications such as high-temperature gas-cooled small modular reactors (HTGR-SMRs) for its capability of retaining excellent mechanical properties and corrosion resistance under operating temperatures between 700℃ and 950℃. While the addition of cerium (Ce) effectively absorbs damaging wavelengths induced by nuclear fission radiation within HTGR-SMRs, potential alterations in the alloy’s thermal properties remain unknown. Laser-Beam Directed Energy Deposition (DED-LB) is an additive manufacturing (AM) process that utilizes focused laser to melt feedstock materials and fabricate complex geometries layer-by-layer. In this work, coefficient of thermal expansion, thermal diffusivity, heat capacity and heat flow of Ce-doped IN617 samples produced by DED-LB were individually evaluated using dilatometry, laser flash analysis, differential scanning calorimetry and differential thermal analysis, respectively, to obtain corresponding results and investigate the effect of cerium addition on the thermal properties of IN617. |
