Description
Technical field
The present invention relates to aluminium alloy technology of preparing, be specially a kind of high strength and high hardness Cast aluminium alloy gold and preparation side thereof
Method.
Background technology
Aluminum, as being only second to the practicality metal material of ferrum, obtains in the industry and is increasingly widely applied, particularly
As during structural material owing to having that density is little, specific strength and specific stiffness is higher, corrosion resistance is good and electrical and thermal conductivity is excellent, reclaim
Easily, the feature such as cryogenic property is good, be widely used in the technology necks such as transportation, Aero-Space, electronic apparatus, automobile making
Territory.
But, existing aluminum alloy materials there is also weak point, as manufacturing process is complicated, cost is high, Wear Resistance is poor,
Intensity is relatively low, uses the most in the presence of a harsh environment and corrosion-deformation easily occurs, and service life shortens.
Summary of the invention
The present invention is to solve the problem that existing aluminum alloy materials exists perishable deformation effect service life, it is provided that one
Plant high strength and high hardness Cast aluminium alloy gold and preparation method thereof.
The present invention adopts the following technical scheme that realization: a kind of high strength and high hardness Cast aluminium alloy gold, is by following matter
The raw material composition of amount percentage ratio: zinc 8.0-15.0wt.%, silicon 4.0-10.0wt.%, copper 1.5-4.5wt.%, ferrum 0.5-2.0
Wt.%, manganese 0.03-0.5wt.%, magnesium 0.03-0.5wt.%, nickel 0.01-0.1wt.%, titanium 0.01-0.1wt.%, surplus is aluminum
And inevitable impurity element.
The chemical property of zinc is active, in air at normal temperatures, and the basic zinc carbonate film that Surface Creation one layer is thin and compact,
Can stop oxidation further, during alumin(i)um zinc alloy system equilbrium phase diagram richness aluminum portions 275 DEG C, zinc dissolubility in aluminum is 31.6%, and
When 125 DEG C, its dissolubility then drops to 5.6%, is simultaneously introduced zinc and magnesium in aluminum, forms hardening constituent MgZn2, produces alloy
Significantly invigoration effect；MgZn2 content from 0.5% bring up to 12% time, can substantially increase tensile strength and yield strength, containing of magnesium
Amount exceedes in the required extra super duralumin alloy of formation MgZn2 phase, and the ratio of zinc and magnesium controls when about 2.7, and stress corrosion cracking resists
Power is maximum；As added copper on the basis of aluminum-zinc-manganese, forming aluminum-zinc-manganese-copper series alloy, its strengthening effect is at all aluminum
In alloy, maximum, is also the important aluminum alloy materials in space flight, aircraft industry, power industry.
Copper is important alloying element, has certain solid solution strengthening effect, and the CuAl2 of Precipitation has significantly in addition
Ageing strengthening effect.
Aluminium alloy adds silicon and can put forward heavy alloyed casting character and corrosion stability, if magnesium and silicon are simultaneously introduced in aluminum formation
Hardening constituent is MgSi, can increase substantially the intensity of alloy after adding copper.
Ferrum existing forms in alusil alloy common are α-AlFeSi and β-AlFeSi, the α-AlFeSi phase of Chinese character shape
The intensity of Alar, hardness can be improved, toughness is reduced seldom；As Fe ＞ 0.5%, lamellar β-AlFeSi can improve mutually
The intensity of alloy also slightly reduces its elongation percentage.Additionally, for pack alloy, a certain amount of Fe content can prevent mucosa, also
The mobility of alloy can be increased.
A kind of high strength and high hardness Cast aluminium alloy gold and preparation method thereof, uses following steps: a, with metal aluminium ingot, aluminum zinc
Intermediate alloy or metal zinc ingot, nonmetal silicon, metallic copper, aluminum manganese intermediate alloy or manganese metal, manganese aluminium intermediate alloy or magnesium metal
Ingot, metallic iron, metallic nickel, Titanium, as the raw material of element each in aluminium alloy, weigh the most former by above-mentioned mass percent
Material；B, being put into by metal aluminium ingot and carry out melting in smelting furnace, smelting temperature is 650-680 DEG C, until being completely melt that making aluminum melts
Body；C, aluminum melt is progressively heated at 750-770 DEG C from 650-680 DEG C, be gradually added in heating process required zinc, copper,
Manganese, ferrum, magnesium and silicon, nickel, titanium, it is thus achieved that aluminium alloy melt；D, aluminium alloy melt is controlled at a temperature of 750-770 DEG C stir
10min, adds the special refining agent of aluminium alloy in whipping process and carries out refine and degasification, and refine is complete, removes melting on liquid level
Agent and scum silica frost, stand about 30min；E, the addition special refining agent of aluminium alloy carry out double refining, all at a temperature of 750-770 DEG C
Even stirring 20min, removes the scum silica frost on liquid level, stands about 30min the most again, cast after on-line filtration and degasification,
Get product.
There is advantages that the tensile strength of aluminum alloy materials casting stretching bar can reach 310Mpa,
Yield strength can reach 225Mpa, and elongation percentage can reach 8%, and Brinell hardness can reach 110HB, has effectively stopped corrosion-deformation
The generation of phenomenon, extends and shortens, and processing technique is rationally reliable, can be used for Aero-Space, telecommunications, vapour service life
High strength and high hardness structural member in the field such as car and weapons and exterior part.
