Abstract
The invention discloses a titanium alloy for casting, which is composed of the following components in percentage by weight: 82.4-87.2% of titanium, 3.6-4.5% of vanadium, 5.6-6.8% of aluminum, 1.3-2.2% of molybdenum, 1.5-2.4% of niobium and 0.8-1.7% of nickel. By adding the vanadium, aluminum, molybdenum, niobium and nickel into the titanium-base alloy, the castability is enhanced, and the alloy has the advantages of excellent strength, excellent fracture toughness, higher product quality and wider application range.
Description
Technical field
The present invention relates to a kind of alloy, be specifically related to a kind of casting titanium alloy.
Background technology
Cast titanium alloy is the titanium alloy for being cast into definite shape foundry goods, and the use temperature of cast titanium alloy is generally 300～400 DEG C at present.General vacuum cooling-shell furnace and the graphite mould fusion casting of adopting produced.Be mainly used in casting the nonrotational property parts such as aero-engine casing, resting support, turning vane, also for rotation parts such as casting impellers, replace stainless steel and be used in chemical field.Along with the constant growth of productivity, existing cast titanium alloy cannot meet the user demand in market gradually.
Summary of the invention
The object of the present invention is to provide a kind ofly improve that castibility, intensity and fracture toughness property are high, the casting titanium alloy of the quality of improving product, quality that use range is wide.
Technical scheme of the present invention is, a kind of casting titanium alloy, described casting is combined by titanium, vanadium, aluminium, molybdenum, niobium and six kinds of metal ingredients of nickel with titanium alloy, described casting is respectively with the shared weight percent of each composition in titanium alloy: described titanium accounts for 82.4%-87.2%, described vanadium accounts for 3.6%-4.5%, and described aluminium accounts for 5.6%-6.8%, and described molybdenum accounts for 1.3%-2.2%, described niobium accounts for 1.5%-2.4%, and described nickel accounts for 0.8%-1.7%.
In a preferred embodiment of the present invention, described casting is specially with the shared weight percent of each composition in titanium alloy: described titanium accounts for 82.4%-87.2%, described vanadium accounts for 3.6%-4.5%, described aluminium accounts for 5.6%-6.8%, described molybdenum accounts for 1.3%-2.2%, described niobium accounts for 1.5%-2.4%, and described nickel accounts for 0.8%-1.7%.
In a preferred embodiment of the present invention, described casting is specially with the shared weight percent of each composition in titanium alloy: described titanium accounts for 82.4%-87.2%, described vanadium accounts for 3.6%-4.5%, described aluminium accounts for 5.6%-6.8%, described molybdenum accounts for 1.3%-2.2%, described niobium accounts for 1.5%-2.4%, and described nickel accounts for 0.8%-1.7%.
Of the present invention is a kind of casting titanium alloy, by add the metallic elements such as vanadium, aluminium, molybdenum, niobium and nickel in the titanium base alloy taking titanium as base, improve castibility, and there is good intensity and fracture toughness property, promoted quality and the use range of product.
Embodiment
Below preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Of the present invention is a kind of casting titanium alloy, described casting is combined by titanium, vanadium, aluminium, molybdenum, niobium and six kinds of metal ingredients of nickel with titanium alloy, described casting is respectively with the shared weight percent of each composition in titanium alloy: described titanium accounts for 82.4%-87.2%, described vanadium accounts for 3.6%-4.5%, described aluminium accounts for 5.6%-6.8%, described molybdenum accounts for 1.3%-2.2%, and described niobium accounts for 1.5%-2.4%, and described nickel accounts for 0.8%-1.7%.
Further, described casting is specially with the shared weight percent of each composition in titanium alloy: described titanium accounts for 82.4%-87.2%, described vanadium accounts for 3.6%-4.5%, described aluminium accounts for 5.6%-6.8%, described molybdenum accounts for 1.3%-2.2%, described niobium accounts for 1.5%-2.4%, and described nickel accounts for 0.8%-1.7%.
Further, described casting is specially with the shared weight percent of each composition in titanium alloy: described titanium accounts for 82.4%-87.2%, described vanadium accounts for 3.6%-4.5%, described aluminium accounts for 5.6%-6.8%, described molybdenum accounts for 1.3%-2.2%, described niobium accounts for 1.5%-2.4%, and described nickel accounts for 0.8%-1.7%.
In addition, can be by regulating the Different Weight per-cent of each composition in alloy, the alloy property height obtaining is differed.
Of the present invention is a kind of casting titanium alloy, by add the metallic elements such as vanadium, aluminium, molybdenum, niobium and nickel in the titanium base alloy taking titanium as base, improve castibility, and there is good intensity and fracture toughness property, promoted quality and the use range of product.
The foregoing is only the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; the variation that can expect without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
