Abstract
The invention discloses a low-cost titanium alloy containing Fe and Mn elements. The low-cost titanium alloy is characterized in that the alloy contains constituent elements of, by mass, 4.5%-6% of aluminum, 4%-6% of iron, 4%-6% of manganese, 0.0%-0.05% of oxygen, 0.0%-0.01% of carbon, 0.0%-0.01% of nitrogen, 0.0%-0.001% of hydrogen, and the balance titanium. The low-cost titanium alloy containing the Fe and Mn elements is excellent in solid solution strengthening effect by the aid of the elements of the Mn, the Fe and the like. The low-cost elements such as the Fe, the Cr and the Mn replace expensive elements such as V, Mo and Nb, so that the manufacturing cost of the titanium alloy is reduced, and moreover the creep resistance, weldability and machining tenacity are good.

Titanium or titanium alloy is a kind of important structural metallic materials that eighties of last century grows up the fifties, and its density is
4.5g/cm3The 58% of left and right, only steel.The specific strength of titanium alloy is high, and corrosion resistance is good, has excellent combination property, is
A kind of important new structural material.First practical titanium alloy is the Ti-6Al-4V alloy that the U.S. in 1954 succeeds in developing,
Hereafter, many countries all recognize the importance of titanium alloy material in the world, in succession research and develop it.Titanium or titanium alloy
Being currently used primarily in space flight and aviation and war industry, other industrial circle usage amount is the lowest.Limit what titanium alloy was widely popularized
One major reason is exactly its high production cost, and in its cost structure, raw material accounts for the 40% of totle drilling cost.Therefore, make
Alloying element (such as V, Nb, Mo etc.) strengthening titanium alloy costly is replaced with cheap alloying element (such as Fe, Cr, Mn etc.)
Performance has important development prospect.
At present conventional titanium alloy α stable element is Al, and Al element and the interaction mechanism of titanium alloy and to titanium
The research of the impact of alloy structure performance comparative maturity.Titanium alloy beta stable element mainly has: Mo, V, Cr, Mn, Fe,
Cu, Ni etc., Mo, the application in existing titanium alloy of the V alloy element widely, alloy designations: TA (10,11,14,15,17,
18,19), TC(3,4,6,9,10,11,12,16,17,18,19), TB(2,3,4,5,6,7,8,9,10) etc. titanium alloy in all
Containing alloying elements such as Mo, V in various degree.But, the alloying element such as V, Mo is expensive, improves being manufactured into of titanium alloy
This, be unfavorable for the application of titanium alloy.
