COPPER-CONTAINING TITANIUM ALLOY AND METHOD OF ITS PRODUCTION Russian patent published in 2024 - IPC C22C14/00 B22F10/28 

FIELD: powder metallurgy.

SUBSTANCE: invention relates to production of complex-shape 3D printing parts, namely, to selective laser fusion of metal powders of titanium-based alloys. Copper-containing titanium alloy contains, wt.%: copper 9.5, aluminum 5.8–7.3, vanadium 3.5–5.3, iron up to 0.6, carbon up to 0.1, silicon up to 0.1, nitrogen up to 0.05, zirconium up to 0.3, oxygen up to 0.2, hydrogen up to 0.015, titanium—the rest. Method of producing a copper-containing titanium alloy involves obtaining a powder composition, layer-by-layer application of powder composition on substrate and selective fusion of layers by laser beam in atmosphere of argon with formation of copper-containing titanium alloy. Powder composition is obtained by mixing powder of alloy VT6, copper powder and aluminum nanopowder at their ratio, wt.%: powder of alloy VT6—90, copper powder—9.5 and aluminum nanopowder—0.5.

EFFECT: obtaining an alloy with high hardness due to minimum porosity; in alloy is provided with uniform distribution of elements.
