Ti-6Al-4V ELI (Grade 23) (L-PBF, Colibrium Additive Ti6Al4V Grade 23, stress-relieved)

Colibrium Additive Ti6Al4V Grade 23 is a low-interstitial Ti-6Al-4V grade printed by laser powder bed fusion, here in the stress-relieved condition. Rapid solidification gives a fine acicular martensitic structure within columnar prior-beta grains along the build direction, with high strength, limited ductility, some anisotropy and high residual stress. Stress relief, usually done on the build plate, lowers that stress and the distortion on removal while largely keeping the fine microstructure. Parts still need support removal and finishing of the rough surface, and are often hot isostatically pressed for fatigue-critical use in aerospace brackets and orthopedic implant components. Every value on this page is read from Colibrium Additive'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.
