Ti-6Al-4V (L-PBF, Velo3D Ti-6Al-4V, annealed)

Velo3D Ti-6Al-4V is that maker's grade of the alpha-beta titanium alloy made by laser powder bed fusion, here in the annealed condition. As built, rapid solidification gives columnar prior-beta grains along the build direction filled with fine acicular martensite, plus high residual stress and a rough surface. Annealing relieves the stress and turns the martensite into a fine alpha-beta structure with better ductility, though some anisotropy between build directions remains. Parts are typically machined on critical surfaces and may be hot isostatically pressed for fatigue-loaded service. They serve as lightweight aerospace brackets, ducts, manifolds and other complex titanium components. Every value on this page is read from Velo3D'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.
