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

Renishaw Ti6Al4V ELI-0406 is that maker's extra-low-interstitial Ti-6Al-4V grade, built by laser powder bed fusion and annealed after printing. As built, rapid solidification gives fine acicular martensite within columnar prior-beta grains along the build direction, with high residual stress and low ductility. Annealing relieves that stress and transforms the martensite to a fine alpha-beta structure, improving ductility, though the columnar texture and any porosity remain. Parts need supports, and their rough surfaces are usually machined where fatigue matters. Uses include orthopaedic implants with lattice regions and lightweight aerospace brackets. 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.
