Definitions
- the present invention relates to a new high and heat resistant aluminum-silicon casting alloy with high thermal conductivity, which is suitable for the production of engine components, in particular for casting cylinder heads and cylinder crankcases.
- AI casting alloys are known in particular in engine construction. AI castings are widely used because of their low specific gravity, ease of molding and ease of processing. Also, through various casting methods, complicated workpieces such as e.g. Make pistons, cylinder heads, crankcases or engine blocks.
- a proven alloy group for the production of engine components are Al-Si alloys. These materials are typically with silicon contents between 4.5 and 18 wt .-%, in some cases up to 24 wt .-%, and with admixtures of magnesium 0.1 to 1, 5 wt.%, Copper between 1 and 4 wt.
- the improvement of the mechanical strength is in this case a deterioration of the thermal shock resistance and the fatigue behavior due to excessive contents on alloying elements such as silicon, copper, magnesium.
- the cylinder heads are subject to high thermo-mechanical loads under operating stress. Since the heat dissipation one of the essential
- the thermal conductivity can affect its life more than the increase in strength or ductility of the cylinder head alloy.
- the patent DE 199 25 666 C1 discloses an aluminum cylinder head alloy with 6.80 to 7.20 wt .-% silicon, 0.35 to 0.45 wt .-% magnesium, 0.35 to 0.45 wt .-% Iron, 0.30 to 0.40 wt% copper, 0.45 to 0.55 wt% nickel and 0.11 to 0.15 wt% titanium.
- the too low copper content of this alloy can not meet the high demands on the heat resistance at temperatures above 250 ° C. With long-term thermal stress already above 150 ° C., strength losses of more than 30% occur.
- the aluminum-silicon alloys from the group EN AC-45000 to EN AC-45400 are known. These alloys contain from 4.5 to 7% by weight of silicon, from 1 to 5% by weight of copper, from 0.5 to 1% by weight of iron, from 0.05 to 0.65% by weight of magnesium and from 0.15 to 2% by weight of zinc. Although these alloys have good mechanical properties due to the high copper and magnesium contents, they have poor thermal conductivity.
- DE 691 10 018 T2 discloses a high-strength cast aluminum alloy with 2.5 to 4.4 wt.% Si, 1, 5 to 2.5 wt.% Cu and 0.2 to 0.5 wt.% Mg, which should improve the alloy in terms of toughness and strength.
- this alloy is not satisfactory in terms of its thermal conductivity.
- the invention has for its object to provide a suitable for the production of engine components alloy having a high thermal conductivity, high strength, heat resistance, good creep strength and sufficient ductility with low susceptibility to corrosion and is also inexpensive.
- This object is achieved by targeted adjustment of a silicon content of 2.6 to 4.5 wt .-% of a copper content of 0.5 to 3 wt .-% of a magnesium content of 0.001 to 0.3 wt.% Of a zirconium content of
- alloy Barium, nitrogen, carbon dissolved, wherein the alloy is preferably a
- thermo-mechanical properties is when the alloy contains from 0.001 to 0.19% by weight of magnesium.
- the silicon content is particularly preferably 3.0 to 4.5 wt .-%.
- thermo-mechanical behavior HCF and TMF
- the thermal conductivity of the alloy at 250 0 C is at least 190 W / mK, more preferably at least 198 WVmK, that is adjusted thereto.
- the silicon content according to the invention By adjusting the silicon content according to the invention, it is possible to set the concentration limits of important strength-increasing alloying elements, such as copper, titanium, zirconium, iron, manganese, chromium, cobalt, molybdenum and depending on the application of other transition elements relatively high, without affecting the thermal conductivity noticeably.
- the alloy according to the invention has excellent thermal conductivity values, which represent an important life-time criterion when using the cylinder head alloys. This gives better thermal shock resistance and better fatigue behavior under thermomechanical stress for this alloy.
- the elements silicon, magnesium, manganese, iron, cobalt, copper, zinc, nickel, vanadium, niobium, molybdenum, chromium, tungsten, beryllium, lead, lithium, yttrium, cerium, scandium, hafnium, silver, zirconium, titanium, Boron, strontium, sodium, potassium, calcium, antimony, sulfur, barium, nitrogen, carbon, it is possible to tailor the properties of the alloy according to the invention to the intended use. For example, the additions of transition elements give the casting a high creep strength and structural strength at elevated temperature, so that no distortion is to be expected during demoulding.
- the alloy contains at least 0.01, more preferably at least 0.03, more preferably at least 0.1, even more preferably at least 0.2% by weight zirconium.
- AI3Zr Phases of high thermal stability by the presence of the dispersion hardening is maintained at temperatures between 150 0 C and 400 0 C and contributes to the thermo-mechanical stability of the casting alloy according to the invention.
- zirconium converts the plate-shaped intermetallic phases, which are particularly in the presence of iron, into Chinese-type forms, which also contributes to improving the elongation at break and thermal conductivity of the alloy according to the invention.
- the zirconium content of the alloy is preferably from 0.001 to 0.8% by weight, more preferably from 0.03 to 0.8% by weight, more preferably from 0.1 to 0.8% by weight, further preferably from 0.2 to 0.8 wt .-%, more preferably 0.3 to 0.5 wt .-%, more preferably 0.001 to 0.5 wt .-%, further preferably 0.03 to 0.5 wt .-%.

- the alloy according to the invention may contain from 0.1 to 1.4% by weight of iron.
- the high iron content in die casting is used to reduce the adhesion tendency.
- Al-Si eutectic and the precipitation of Al 2 Cu and Mg 2 Si phases in the alloy according to the invention which in turn are influenced by a suitable heat treatment.
- the limitation of the magnesium content to a maximum of 0.3 wt .-%, preferably 0.19 wt .-%, causes the elongation values of the alloy according to the invention in the casting state does not fall below 4%.
- the magnesium content In order to achieve a significantly higher elongation, however, the magnesium content must be limited to a maximum of 0.15% by weight, more preferably to a maximum of 0.1% by weight.
- the setting of the lowest possible magnesium contents also ensures at the same time excellent thermal conductivity of the alloy according to the invention.
- a certain amount of titanium or boron and / or carbon in combination with titanium is used for grain refining, the addition of these elements with aluminum-titanium, aluminum-boron, aluminum-titanium-boron and aluminum-titanium-carbon Pre-alloys takes place.
- the ⁇ -aluminum mixed crystal can also be grain-refined by zirconium additions of 0.2 to 0.8 wt%.
- a good grain refining contributes significantly to the improvement of the mechanical properties and castability of the alloy according to the invention.
- the master alloys AITi6, AIB4, AITi3C0,15, AIZMO and AITiI, 8B1, 8 were particularly effective.
- the melt can be degassed by flushing gas, purge gas tablets or by vacuum.
- castings produced from the alloy according to the invention can be subjected to all heat treatments.
- Exemplary embodiment chill casting
- the above-mentioned alloy was used in a mold according to DIN 29531 at the casting temperature of
- the drained sample rods were stored ahead of an additional 100 hours at 250 0 C for all alloys.
- Table 1 gives a comparison of the alloy according to the invention with conventional alloys for engine components.
- the determination of the thermal diffusivity was carried out with a laser flash apparatus.
- the specific heat capacity was determined with a high-temperature calorimeter.
- Table 1 gives a comparison of the alloy according to the invention with conventional alloys for engine components.
