Ti-6Al-4V (L-PBF, Colibrium Additive Ti6Al4V Grade 5, as-built)

Colibrium Additive Ti6Al4V Grade 5 is that maker's Ti-6Al-4V processed by laser powder bed fusion, here in the as-built condition before any heat treatment. Rapid solidification of the melt pool gives a fine acicular alpha-prime martensite within columnar prior-beta grains elongated along the build direction. As a result, strength is high, ductility is limited and properties differ between build directions. As-built parts carry high residual stress, rough surfaces and support structures, so they are normally stress relieved or hot isostatically pressed, removed from the plate and machined on critical faces. Typical uses are lightweight aerospace brackets and housings, medical device components and lattice structures. 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.
