A beta titanium alloy for additive manufacturing

Abstract

A titanium-based alloy composition consisting in weight percent, of: 3.0 to 7.0% aluminium, 3.0 to 10.0% vanadium, 3.0 to 10.0% molybdenum, 2.0 to 7.0% tin, 0.0 to 6.0% zirconium, 0.0 to 5.0% niobium, 0.0 to 0.5% iron, 0.0 to 4.0% chromium, 0.0 to 2.0 tungsten, 0.0 to 0.5 % nickel, 0.0 to 0.5% tantalum, or between 0.0 to 2. tantalum when the sum of niobium and tantalum is 5.0% or less, 0.0 to 0.5% cobalt, 0.0 to 0.75% silicon, 0.0 to 0.5% boron, 0.0 to 0.5% carbon, 0.0 to 0.5% oxygen, 0.0 to 0.5% hydrogen, 0.0 to 0.5% nitrogen, 0.0 to 0.5% palladium, 0.0 to 0.5% lanthanum, 0.0 to 0.5% manganese or 0.0 to 2.5% manganese when the sum of chromium and manganese is 4.0 wt. % or less, 0.0 to 1.0% hafnium, the balance being titanium and incidental impurities which satisfies the following relationship: 0.027V+0.178Fe+0.055(Mo+0.5W)+0.016Zr+0.044Cr+0.033(Nb+Ta)+0.053Sn>1.0 where Mo, W, V, Zr, Sn, Cr, Fe, Ta and Nb represent amounts of molybdenum, tungsten, vanadium, zirconium, tin, chromium, iron, tantalum and niobium in wt. % respectively.
