Ti-6Al-4V ELI (Grade 23) (L-PBF, EOS Titanium Ti64ELI)

EOS Titanium Ti64ELI is a laser powder bed fusion grade of Ti-6Al-4V ELI (Grade 23). Rapid solidification gives a fine acicular martensite within columnar prior-beta grains along the build direction, so as-built parts are strong but less ductile and somewhat anisotropic. Parts carry high residual stress and are stress relieved before removal from the plate, and are often hot isostatically pressed to close porosity and improve fatigue life. Overhangs need supports, and the rough as-built surface is usually machined on fatigue-critical features. Typical parts are orthopedic and dental implants with lattice structures and lightweight aerospace components. Every value on this page is read from EOS'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.
