Disclosed are an aluminum-scandium alloy target with high scandium content and a preparation method thereof. The method comprises: preparing aluminum and scandium; melting the scandium; mixing the aluminum into the scandium, smelting and cooling to obtain an aluminum-scandium alloy through a plurality of cycles; ball-milling the alloy to obtain alloy powder and drying in vacuum, then pre-pressing and sintering in vacuum to obtain an aluminum-scandium alloy target billet; performing a thermal deformation process on the target billet to obtain the target, comprising hot forging, hot rolling and finish machining. In the present disclosure, the target has more uniform structure and chemical composition, higher relative density (up to 99.0% or more), finer grain size and higher ductility; reduce defects of shrinkage cavity and porosity, save material cost, solve problem of alloys with high brittleness, unable to process targets, meeting the requirements on wiring materials for large-scale integrated circuits.

A method of titanium wire additive manufacturing is disclosed. The method may comprise mixing a plurality of powdered metals comprising titanium, iron, vanadium, and aluminum to produce a powder blend, sintering the powder blend to form a billet, performing a wire forming operation to produce a worked wire, heat treating the worked wire to produce a heat treaded wire, loading the heat treated wire into a wirefeed additive manufacturing machine, and producing a metallic component from the heat treated wire. The titanium may be a titanium hydride powder.
