Description

Aldural
Technical field
The present invention relates to a kind of aluminium alloy, be specifically related to a kind of aldural.Belong to metallic substance technical field of smelting.
Background technology
Aluminium alloy has that density is little, specific tenacity and the feature such as specific rigidity is higher, solidity to corrosion is good and electrical and thermal conductivity is excellent, reclaim easily, low-temperature performance is good, is widely used in the fields such as communications and transportation, aerospace, electronic apparatus.The main alloy element of aluminium alloy has silicon, copper, magnesium, zinc etc., and the structure property of different alloying elements and consumption alloy thereof has different impacts.
Al-Zn-Mg-Cu aluminum alloy be the sixties in 20th century with aerospace material for background is developed and the class high-performance aluminium alloy grown up, there is the series of advantages such as lightweight, high strength, high tenacity and low cost, be widely used in the fields such as aviation, communications and transportation, naval vessels and weapons, there is high using value.But traditional Al-Zn-Mg-Cu aluminum alloy, because the Zn content in aluminium alloy controls about 5.5%, cause the intensity of aluminium alloy to be difficult to break through 700MPa, and the over-all properties of aluminium alloy is not good.
Summary of the invention
The object of the invention is, for overcoming above-mentioned the deficiencies in the prior art, to provide a kind of nickel base superalloy.
For achieving the above object, the present invention adopts following technical proposals:
A kind of aldural, described aldural is made up of following component by weight percentage: Zn:2.5-6.5%, Mg:2.3-4.0%, Cu:3.1-5.5%, Mn:0.01-0.1%, Zr:2.0-6.2%, Ti:3.0-5.5%, Nb:4.5-6.0%, Ta:2.5-3.5%, Be:0.03-0.06%, Co:0.8-1.2%, Ru:1.8-3.0%, Hf:0.05-0.2%, Re:0.02-0.1%, Si :≤0.1%, Fe :≤0.3%, P :≤0.005%, S :≤0.005%, Y≤0.08%, all the other are Al and inevitable trace element.
Further, described aldural is made up of following component by weight percentage: Zn:3.5-5.5%, Mg:2.5-3.5%, Cu:3.5-5.0%, Mn:0.05-0.08%, Zr:3.0-5.2%, Ti:3.5-5.0%, Nb:5.0-5.5%, Ta:2.8-3.2%, Be:0.04-0.05%, Co:0.9-1.0%, Ru:2.0-2.5%, Hf:0.09-0.1%, Re:0.05-0.08%, Si :≤0.1%, Fe :≤0.3%, P :≤0.005%, S :≤0.005%, Y≤0.08%, all the other are Al and inevitable trace element.
Further, described aldural is made up of following component by weight percentage: Zn:4.0%, Mg:3.0%, Cu:4.0%, Mn:0.06%, Zr:3.2%, Ti:3.6%, Nb:5.2%, Ta:3.0%, Be:0.045%, Co:0.95%, Ru:2.2%, Hf:0.095%, Re:0.06%, Si:0.1%, Fe:0.3%, P:0.005%, S:0.005%, Y0.08%, all the other are Al and inevitable trace element.
Further, the mass percent of described inevitable microalloy element is 0.001%-0.01%.
Strontium is usually used in the Metamorphism treatment of aluminium alloy, can reduce solution time, significantly promotes the performance of Al-Si casting alloy, strontium refinement Al-Fe-Si intermetallic compound, and makes acicular beta phase in version be phase that is block and Chinese character shape, improves tensile strength; Strontium is as long-acting alterant in addition, refined cast structure, makes alloying elements distribution even, and crystal boundary area, crystal boundary internal component difference are less, improve the erosion resistance of alloy.
In aluminium alloy, add Zr, Hf of trace, the anti-stress corrosion performance of aluminium alloy, quenching sensitive, anti-recrystallizing ability and fracture property can be improved.
The interpolation of element Ru, Ta, can improve the recrystallization temperature of aluminium alloy, and hot strength, structural stability, welding property and corrosion resistance all significantly improve, and the brittle phenomenon easily produced during long term operation under high temperature can be avoided, can intensity be improved simultaneously.
Titanium in aluminium alloy not only deoxidation can produce oxide compound but also can produce ageing strengthening effect, and can reduce weld metal simultaneously and produce pore, the defect such as loose, manganese, silicon combined deoxidation are also the most effective reductors.
The impact of phosphorus, the sulphur Resistance of Weld Metal when welding high-chromium-nickel alloy is more more responsive than other alloying element.Matter of utmost importance is the solidification cracking of weld seam.Phosphorus, the sulphur solubleness in high-chromium-nickel alloy is very little, but easily forms grain boundary segregation, produces the sulfide of low melting point eutectic, promotes the generation of solidification cracking.Therefore phosphorous, sulfur content must be controlled in aluminum alloy materials.
Rare earth have in aluminium alloy rotten, purification and Microalloying Effect, rare earth element can change Morphology of Eutectic Silicon in Al-Si Foundry Alloys in Al-Si alloy, and intermetallic compound is uniformly distributed, thus improve alloy strength and corrosion resistance nature, and the effect of crystal grain thinning in heat treatment process, increases its structural strength, can also improve its corrosion resistance and frictional behaviour, improve its work-ing life, reduce costs.
The present invention prepare aldural, its yield strength can reach 750Mpa, and tensile strength reaches more than 950Mpa, and unit elongation, about 18%, has good ageing resistance stability, ductility and comprehensive obdurability.
