Claim Text:
1. A method for forming a near β-titanium alloy comprising (4.0-6.0)% Al—(4.5-6.0)% Mo—(4.5-6.0)% V—(2.0-3.0)% Cr, (0.2-0.5)% Fe—(0.2-2.0)% Zr and the balance Ti, the method comprising the steps of: (i) a fabrication of a consumable electrode comprising titanium with incorporation of alloying elements into an electrode charge material by combining a complex master alloy comprising Al, Mo, Cr, V, Ti with pure elements Fe and Zr; and (ii) the β-titanium alloy is formed by at least a double melting of the consumable electrode, wherein the first melting is done by vacuum arc melting or skull melting, and the second and subsequent meltings are done by vacuum arc melting.
