Ti-6Al-4V (L-PBF, Xact Metal Ti-6Al-4V Grade 5 (Linde), stress-relieved)

Xact Metal Ti-6Al-4V Grade 5 (Linde) is a Grade 5 titanium alloy printed by laser powder bed fusion, here in the stress-relieved condition. As printed, rapid solidification gives a fine acicular martensitic structure in columnar prior-beta grains along the build direction, with high residual stress, rough surfaces and a need for supports. Stress relief, usually done before parts are cut from the build plate, limits distortion and partly tempers the martensite but does not close porosity, so fatigue-critical parts are often also hot isostatically pressed. Typical parts are lightweight aerospace brackets, motorsport components and medical devices. Every value on this page is read from Xact Metal'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.
