Ti-6Al-4V (wire-DED, Meltio Titanium 64, as-built)

Meltio Titanium 64 in the as-built condition is Ti-6Al-4V wire deposited by laser wire-feed directed energy deposition and left without heat treatment. Layer-by-layer solidification produces coarse columnar prior-beta grains along the build direction with fine acicular alpha inside, so strength and ductility differ between build directions. Parts carry residual stress and a wavy, stepped surface, so they are near-net shapes that are machined and usually stress relieved before service. Typical uses are large titanium preforms, features added to existing parts and repair of titanium components, often on hybrid machines that deposit and machine in one setup. Every value on this page is read from Meltio'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.
