Abstract
The invention discloses a low-cost beta titanium alloy composed of components of, by weight: 1.5-4.5% of aluminum, 7-14% of chromium, 0-1.5% of iron, 0-1.5% of nickel, 0-3% of tin, and balance of titanium and inevitable impurities. Essential elements of the titanium alloy provided by the invention do not include noble metals such as zirconium, molybdenum, and vanadium, such that the manufacturing cost of the beta titanium alloy is reduced. Also, the mechanical properties of the beta titanium alloy can satisfy titanium alloy mechanical property requirements of certain industries. Therefore, the market prospect of the low-cost beta titanium alloy is good.
Description
Technical field
The present invention relates to the titanium alloy technical field, relate in particular to a kind of beta-titanium alloy cheaply.
Background technology
Beta-titanium alloy is mainly used in aerospace field, and its working temperature is about 500 ℃.Therefore the element that contains a large amount of raising high-temperature behaviors in the beta-titanium alloy commonly used like zirconium, molybdenum, vanadium etc., causes cost to raise, and limited its large-scale popularization and application aspect civilian.But beta-titanium alloy has than excellent processing manufacturability, when higher-strength, has higher fracture toughness property simultaneously, and to the low propensity property of hydrogen embrittlement, therefore the exploitation of low-cost beta-titanium alloy has market potential.
Summary of the invention
In view of this, the present invention provides one type of beta-titanium alloy cheaply.
Beta-titanium alloy cheaply of the present invention, said titanium alloy is made up of following weight percent component: aluminium 1.5～4.5%, chromium 7～14%, iron 0～1.5%, nickel 0～1.5%, tin 0～3%, all the other are that titanium and unavoidable impurities are formed.
Can finely tune the titanium alloy that obtains different mechanical properties to above-mentioned element according to different demands to the titanium alloy mechanical property.
The total weight percent of carbon, hydrogen, oxygen, nitrogen is less than 0.4% in the said impurity.
Titanium alloy of the present invention can adopt general preparing method's production of titanium alloys such as vacuum consumable smelting and press working.The total weight percent of carbon, hydrogen, oxygen, nitrogen is no more than 0.4 in the control impurity.Said chromium element adds with the aluminium chromium hardener form, and iron adds with the pure iron form, and tin adds with aluminium tin master alloy form, and nickel adds with the pure nickel form, thereby guarantees the accuracy of alloying constituent and the consistence that homogeneity is guaranteed the alloy material performance.
Do not contain precious metal zirconium, molybdenum, vanadium in the basic element of titanium alloy of the present invention, thereby reduced the manufacturing cost of beta-titanium alloy; Mechanical property also can satisfy the demand of some industries to the titanium alloy mechanical property, and market outlook are wide.
Embodiment
In conjunction with specific embodiments a kind of low-cost beta-titanium alloy of the present invention is sketched.
Low-cost beta-titanium alloy of the present invention, said titanium alloy is made up of following weight percent component: aluminium 1.5～4.5%, chromium 7～14%, iron 0～1.5%, nickel 0～1.5%, tin 0～3%, all the other are that titanium and unavoidable impurities are formed.
With the alloy material thorough mixing, be pressed into consumable electrode by said ratio, in vacuum arc fumace, be smelted into ingot casting, can be processed into the titanium alloy product of all size kinds such as bar, sheet material, tubing, band, wire rod.
Titanium alloy of the present invention does not contain precious metal zirconium, molybdenum, vanadium etc., thereby has reduced the manufacturing cost of beta-titanium alloy, and performance also can satisfy the demand of different industries to beta-titanium alloy.
The embodiment summary sheet
The sample of above data is sheet coupon.
