Description
Casting of an Aluminium Alloy The invention concerns a casting of an aluminium alloy with good heat resistance.
s For thermally stressed components today normally AISi alloys are used, where the heat resistance is achieved by the additi~~n of Cu to the alloy. Copper, however, also increases the heat crack tendency and has a negative effect on the castability. Applications in which particular heat resistance is required normally occur in the field of cylinder heads in automobile construction, see e.g. F.J.
Feikus, ~o "Optimisation of Aluminium Silicon Casting Alloys for Cylinder Heads", Giesserei-Praxis 1999, Vol. 2, pages 50 - 57.
WO-A-0043560 discloses an aluminium alloy with 2.5 - 7.0 w.% Mg, 1.0 - 3.0 w.%
Si, 0.3 - 0.49 w.% Mn, 0.1 - 0.3 w.% Cr, max. 0.15 w.% Ti, max. 0.15 w.% Fe, ~5 max. 0.00005 w.% Ca, max. 0.00005 w.% Na, max. 0.0002 w.°!°
P, other contaminants individually max. 0.02 w.% .and aluminium as the remainder, for the production of safety components in diecasting, squeeze casting, thixoforming and thixoforging processes.
2o The invention is based on the object of preparing an aluminium alloy with good heat resistance suitable for the production of thermally stressed components.
The alloy is particularly suitable for gravity diec:asting, low pressure chilled casting and sand casting.
2s Components cast from the alloy should gave a high strength in connection with high ductility. The desired mechanical properties of the component are defined as follows:
Yield strength Rp0.2 > 170 MPa 3o Tensile strength Rm > 230 MPa Elongation at fracture A5 > 6%
Because of the applications, the corrosion tendency of the alloys should be kept as low as possible and the alloy muss: have a correspondingly good fatigue strength. The castability of the alloy should be better than that of the AISiCu casting alloys which are currently used, and the alloy should have no tendency to heat cracks.
The term "casting" includes, as well as the pure components produced solely by casting, those cast as a premould and subsequently formed to the final dimensions by hot or cold shaping.
o Examples of pure castings are those which are produced exclusively by sand casting, gravity diecasting, low pressure chilled casting, diecasting, thixocasting or squeeze casting.
Forming operations performed on a cast premould by shaping are for example ~5 forging and thixoforging.
The object according to the invention is achieved by an aluminium alloy with 2 to 4 w.% magnesium 0.9 to 1.5 w.% silicon 20 0.1 to 0.4 w.% manganese 0.1 to 0.4 w.% chromium max. 0.2 w.% iron max. 0.1 w.% copper max. 0.2 w.% zinc 25 max. 0.2 w.% titanium max. 0.3 w.% zirconium max. 0.008 w.% beryllium max. 0.5 w.% vanadium with aluminium as the remainder, with farther elements and production-induced 3o contaminants individually max. 0.02 w.%, total max. 0.2 w.%.
The following content ranges are preferred for the individual alloy elements:
Mg 2.5 to 3.5 w.%, in particular 2.7 to 3.3 w.%
Si 0.9 to 1.3 w.%
Mn 0.15to0.3w.%
Cr 0.15to0.3w.%
Ti 0.05 to 0.15 w.%
Fe max. 0.15 w.%
Cu max. 0.05 w.%
Be 0.002 to 0.005 w.%
V 0.01to0.1w.%
Zr 0.1 to 0.2 w.%
The effect of the alloy elements can be characterised approximately as follows:
Silicon in conjunction with magnesium leads to a corresponding hardening where in particular thermal hardening is of interest. Preferred is heat treatment to a state T6 e.g. solution annealing at 550°C for 1 ~ hours with subsequent artificial ageing at 160 - 170°C for 8 to 10 hours.
The combination of manganese and chromium leads to good heat resistance at a sustained temperature of up to 180°C.
Titanium and zirconium are used for grain refining. Good grain refining makes a substantial contribution to an improvement: in casting properties.
Beryllium in conjunction with vanadium reduces the dross formation.
A preferred area of application of the castings according to the invention is thermally stressed components, in particular pressure vessels, compressor housings and engine components su~;h as cylinder heads in automobile construction. The components are preferably produced in the sand casting or chilled casting process.
Further advantages, features and details cf the invention arise from the description below of preferred embodiment examples and the drawing which shows:
Figs. 1 - 3 tensile strength, yield strength and elongation at fracture as a function of temperature after 500 hours sustained temperature load for an alloy according to the invention and a comparison alloy according to the prior art.
An alloy according to the invention reference AIMg3Si1 MnCr and a comparison alloy reference AISi7MgCu1 by F.J. Feilcus, "Optimisation of Aluminium Silicon Casting Alloys for Cylinder Heads", Giesserei-Praxis 1999, Vol. 2, pages 50 -57, with the compositions given in table 1, were compared with regard to long-term behaviour under sustained temperature load.
Table 1: Chemical Composition of Alloys (in w.%) Alloy Si Fe Cu Mn Mg Cr Zn Ti Be V Zr AISi7MgCu16.97 0.110.940.0050.;38 0.0080.03 AIMg3Si1MnCr1.10 0.070.0010.20 3.2 0.210.0020.120.0030.030.0005 The alloy according to the invention was cast in a trial rod mould according to Diez for round rods 16 mm diameter. The rnechanical properties of yield strength (Rp0.2), tensile strength (Rm) and elongation at fracture (A5) were determined on the trial rods in state T6 (165°C/6 hours) after a sustained temperature load of 500 2o hours at various temperatures. The corresponding values for the comparison alloy were taken from the above article by F.J. I=eikus. The results are shown in fig. 1 in diagram form.
The alloy AIMg3Si1 MnCr according to the invention admittedly does not reach the peak values of the comparison alloy AISi7MgCu1 with regard to yield strength and tensile strength, but in its temperature behaviour is "less changeable". This changeability has a disruptive effect in operation insofar as slight changes in temperature can cause great changes in mechanical properties. The yield strength of the alloy according to the invention remains at around the same level up to 3o around 180°C, gradually falls away up to 200°C, and only above around 200°C
begins to decrease continuously. The continuous decrease takes place with a lesser gradient than the alloy AISi7MgCu1.
With regard to the elongation at fracture, the alloy according to the invention is s characterised by an almost constant value up to 180°C. High elongation values give a favourable fracture/failure behaviour. A visible deformation precedes the break of the component. Above 180°C the elongation rises continuously.
In the comparison alloy AISi7MgCu1, the cle~~r hardening effect can be seen. Low elongation values cause an unfavourable failure behaviour i.e. the component only ~o deforms slightly or not at all. Under loa~~ peaks the component breaks without warning.
s For thermally stressed components today normally AISi alloys are used, where the heat resistance is achieved by the additi~~n of Cu to the alloy. Copper, however, also increases the heat crack tendency and has a negative effect on the castability. Applications in which particular heat resistance is required normally occur in the field of cylinder heads in automobile construction, see e.g. F.J.
