Ti-6Al-4V ELI (Grade 23) (L-PBF, Renishaw Ti6Al4V ELI-0406, HIP)

Renishaw Ti6Al4V ELI-0406 is the maker's extra-low-interstitial Ti-6Al-4V (Grade 23) grade printed by laser powder bed fusion and then hot isostatically pressed. As built, it has fine acicular α' martensite in columnar prior-β grains along the build direction, high residual stress, rough downskin surfaces and supports to remove. HIP closes internal porosity and transforms the martensite to lamellar α+β, trading some strength for ductility and better fatigue life, though surface roughness remains and critical faces are usually machined. Parts in this condition are used for fatigue-loaded aerospace brackets and for orthopaedic implants, including porous lattice designs. 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.
