Ti-6Al-4V ELI (Grade 23) (L-PBF, Nikon SLM Solutions Ti6Al4V ELI (Grade 23), HIP)

Nikon SLM Solutions Ti6Al4V ELI (Grade 23) is that maker's extra-low-interstitial Ti-6Al-4V grade, printed by laser powder bed fusion and then hot isostatically pressed. As built, rapid cooling gives fine acicular martensite in columnar prior-beta grains along the build direction, with residual stress and scattered porosity. HIP closes internal pores and coarsens the martensite into a lamellar alpha-beta structure, improving ductility and fatigue life at some cost in strength. It does not remove the rough surface or close surface-connected pores, so parts are usually machined after support removal. It is used for implant components, aerospace brackets and other fatigue-loaded titanium parts. 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.
