Inconel 718 (L-PBF, Nikon SLM Solutions IN718, heat-treated)

Nikon SLM Solutions IN718 is that maker's grade of Inconel 718 printed by laser powder bed fusion, here in the heat-treated condition. As built, it has a fine cellular structure with niobium segregation, columnar grains along the build direction and residual stress, so parts are stress relieved before removal from the build plate and supports. Solution treatment and aging precipitate the gamma double prime and gamma prime phases that strengthen the alloy, though some anisotropy between build directions often remains. Printed parts serve as gas turbine and rocket engine components such as combustor hardware, brackets, manifolds and injectors. Every value on this page is read from Nikon SLM Solutions' own material data sheet — quoted, cited and dated — and is the maker's statement about printed material, not a measurement by MatWorld; none has yet been reviewed by a person.
