Inconel 718 (L-PBF, Renishaw In718-0405, aged)

Renishaw In718-0405 is that maker's Inconel 718 grade, made by laser powder bed fusion and given an ageing treatment. As printed, the alloy has a fine cellular-dendritic structure with niobium segregation, columnar grains along the build direction and high residual stress, so parts need supports and stress relief before removal from the plate. Ageing precipitates the strengthening gamma double prime and gamma prime phases, raising strength and hardness, while the columnar texture and some anisotropy remain. Printed parts serve gas turbine and rocket engine hardware such as brackets, combustor and fuel system components, and heat exchangers. Every value on this page is read from Renishaw's 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.
