Description
Technical field
The present invention relates to a kind of aluminum alloy casting with good heat resistance.
Background technology
At present, for the part that is subjected to thermal stresses, generally use the AlSi alloy, wherein thermotolerance realizes by add Cu in alloy.But copper also can strengthen the hot tearing trend, and castability is had negative impact.The stable on heating application of special requirement mainly is the cylinder head field in automobile making, for example referring to F.J.Feikus, " Optimierung von Aluminium-Silicium-Gusslegierungen f ü r Zylinderk pfe ", Giesserei-Praxis 1999, the 2nd, the 50-57 page or leaf.
WO-A-0043560 discloses a kind of aluminium alloy, contain 2.5-7.0 weight %Mg, 1.0-3.0 weight %Si, 0.3-0.49 weight %Mn, 0.1-0.3 weight %Cr, maximum 0.15 weight %Ti, maximum 0.15 weight %Fe, maximum 0.00005 weight %Ca, maximum 0.00005 weight %Na, maximum 0.0002 weight %P, other impurity of the maximum 0.02 weight % of difference and the aluminium of surplus, to be used for making the breaking piece of diecasting, casting-forging method, thixotropic forming or thixotroping forging process.
Summary of the invention
Purpose of the present invention is to provide a kind of aluminium alloy with good heat resistance that is suitable for being subjected to the manufacturing of thermal stresses part.This alloy especially is fit to gravity diecasting, low-pressure chill casting and sand mold casting.
The part of alloy casting should have high strength and high ductibility thus.The part machinery performance of expectation is as follows:
Yield strength Rp0.2＞170Mpa
Tensile strength Rm＞230Mpa
Extension at break A5＞6%
Because its purposes, the corrosion trend of alloy should keep low as far as possible, and this alloy must have corresponding good fatigue strength.The castability of alloy should be better than the AlSiCu casting alloy of use at present, and alloy should not have the hot tearing trend.
Term " foundry goods " not only comprises the pure part of making by casting fully, comprises that also those are by casting the prefabricated part that forms final dimension then by thermoforming or cold-forming.
The example of pure foundry goods is those parts of making by sand mold casting, gravity diecasting, low-pressure chill casting, diecasting, thixotroping casting or casting-forging method fully.
The forming operation that precast piece is carried out for example is to forge and the thixotroping forging.
The objective of the invention is that the following aluminium alloy formed realizes by having:
2-4 weight %Mg
0.9-1.5 weight %Si
0.1-0.4 weight %Mn
0.1-0.4 weight %Cr
Maximum 0.2 weight %Fe
Maximum 0.1 weight %Cu
Maximum 0.2 weight %Zn
Maximum 0.2 weight %Ti
Maximum 0.3 weight %Zr
Maximum 0.008 weight %Be
Maximum 0.5 weight %V
And the aluminium of surplus, wherein the content of other element and the impurity introduced in the mill mostly is 0.02 weight % respectively most and total amount mostly is 0.2 weight % most.
The preferred following content range of each alloying element:
Mg 2.5-3.5 weight %, especially 2.7-3.3 weight %
Si 0.9-1.3 weight %
Mn 0.15-0.3 weight %
Cr 0.15-0.3 weight %
Ti 0.05-0.15 weight %
The maximum 0.15 weight % of Fe
The maximum 0.05 weight % of Cu
Be 0.002-0.005 weight %
V 0.01-0.1 weight %
Zr 0.1-0.2 weight %
The effect of alloying element can roughly characterize as follows:
Silicon produces corresponding sclerosis, particularly heat embrittlement together with magnesium.Preferably be heat-treated to the T6 state, for example 550 ℃ of solution annealing 12 hours and then at 160-170 ℃ of temper(ing) 8-10 hour.
The good heat resistance of the combination results of manganese and chromium under lasting temperature up to 180 ℃.
Titanium and zirconium are used for grain refining.Good grain refining has very great help to improving castability.
Beryllium reduces the formation of waste residue together with vanadium.
A preferred application area according to foundry goods of the present invention is the cylinder head that is subjected in thermal stresses part, particularly pressurized vessel, compressor case and engine components such as the automobile making.These parts preferably use sand mold casting or the manufacturing of chill casting technology.
Other advantage of the present invention, feature and details are recorded and narrated in the explanation to preferred embodiments and drawings below.
Description of drawings
Tensile strength, yield strength and the extension at break of the comparative alloy of Fig. 1-3 alloy of the present invention and prior art behind 500 hours lasting temperature loading is with the variation of temperature curve.
Embodiment
To have shown in the table 1 form according to alloy A lMg3Si1MnCr of the present invention and comparative alloy AlSi7MgCu1 (F.J.Feikus, " Optimierung von Aluminium-Silicium-Gusslegierungen f ü r Zylinderk pfe ", Giesserei-Praxis 1999, the 2nd, the 50-57 page or leaf) compare in the long-term behaviour that continues under the temperature loading.
Table 1: the chemical constitution of alloy (weight %)
| Alloy | Si | ?Fe | Cu | ?Mn | ?Mg | ?Cr | ?Zn | ?Ti | ?Be | ?V | ?Zr |
| ?AlSi7MgCu1 | ?6.97 | ?0.11 | ?0.94 | ?0.005 | ?0.38 | ?0.008 | ?0.03 | ||||
| ?AlMg3Si1MnCr | ?1.10 | ?0.07 | ?0.001 | ?0.20 | ?3.2 | ?0.21 | ?0.002 | ?0.12 | ?0.003 | ?0.03 | ?0.0005 |
To in proof stick model, be cast into the pole of diameter 16mm according to alloy of the present invention according to Diez.Measurement pole behind 500 hours lasting temperature loadings of differing temps is yield strength (Rp0.2), tensile strength (Rm) and extension at break (A5) in the mechanical property of state T6 (165 ℃/6 hours).Measure the part of above-mentioned F.J.Feikus, obtain the respective measurement values of comparative alloy.The result is shown among Fig. 1.
Though according to alloy A lMg3Si1MnCr of the present invention at the peak value that does not reach comparative alloy AlSi7MgCu1 aspect yield strength and the tensile strength, its temperature performance " mutability is less ".This mutability has destruction in force, and the slight change of temperature will cause the great variety of mechanical property.The yield strength of alloy of the present invention is all remaining on about same level up to about 180 ℃, reduces gradually up to about 200 ℃, only reduces continuously about just the beginning more than 200 ℃.The described gradient that reduces continuously is less than alloy A lSi7MgCu1.
For extension at break, be characterised in that all be an almost constant value up to 180 ℃ according to alloy of the present invention.High extension at break value can provide favourable fracture/failure behaviour.Before breaking, part can produce tangible distortion.More than 180 ℃, extension at break increases continuously.In comparative alloy AlSi7MgCu1, can see tangible hardening effect.Low stretch value causes disadvantageous failure behaviour, i.e. a part slight deformation or not distortion.At place, load peak, part has no omen ground and breaks.
