Definitions

the invention relates to a bondable aluminum-silicon die cast alloy, a method for producing a die-cast component from the alloy and a body component with a die-cast component.
the cast components produced with these aluminum-silicon die cast alloys are usually subjected to a T5, T6 or T7 heat treatment in accordance with DIN EN 515.
a T5 heat treatment results in components with good dimensional stability and high strength and T6 or T7 heat treatment gives components with good deformation properties and high strength at the same time.
the EP 2 735 621 A1 an aluminum alloy for higher strength components with a yield strength Rp 0.2 > 120MPa and a simultaneous elongation at break A> 7% as cast, a yield strength Rp 0.2 > 200 MPa and a high elongation at break A> 6% after a T5 heat treatment or a Yield strength Rp 0.2 > 200 MPa and simultaneously high elongation at break A> 9% after a T6 heat treatment, in particular for structural and chassis parts of a motor vehicle, containing 9 to 11.5 wt.% Silicon, 0.45 to 0.8 wt % Manganese, 0.2 to 1.0% by weight magnesium, 0.1 to 1.0% by weight copper, max. 0.2% by weight of zinc, max.
an aluminum-silicon casting alloy containing 5 to 12 mass% silicon, 0.5 to 3.0 mass% zinc, 0.1 to 0.7 mass% magnesium, 0.2 to 0.8 mass% manganese, 0.05 to 0.3 Ma% zirconium, a maximum of 0.05 Ma% and a maximum of 0.4 Ma% impurities and balance aluminum.
This publication also describes a method of manufacturing a die-cast component wherein a casting member is cast from one of the proposed casting alloys and after casting the casting member is subjected to a heat treatment to the condition T5, T6 or T7.
the aluminum-silicon casting alloy has a very good flowability for components with wall thicknesses below 2 mm and the components produced therefrom are characterized by a high strength and at the same time a good deformability.
a manganese content (Mn) of 0.3 to 0.8% by weight improves mold cavity mold release at low iron contents ⁇ 0.3% by weight.
Magnesium content (Mg) of min. 0.25 wt.% Leads to the formation of hardening Mg 2 Si phases, the upper limit of 0.5 wt.% Prevents excessive embrittlement of the material.
Zinc (Zn) is used for further strength enhancement by solid solution hardening of the alloy.
the zinc content in the aluminum-silicon die-casting alloy according to the present invention is limited to a maximum of 0.35 wt.%, Since a higher content greatly reduces the adhesive adhesion when installing such a component, and increases the tendency to corrosion.
a finer grain can be formed by the addition of zirconium (Zr).
the optimum content is between 0.05% by weight and 0.30% by weight of zirconium.
strontium content (Sr) in the range of 0.006 wt.% To 0.025 wt.%, Refining of the alloy according to the present invention can be achieved.
the objects of the present invention are particularly well resolved, provided that the magnesium content in the alloy more than 0.35 wt.% To 0.50 wt. %, preferably in the range of 0.38 wt.% To 0.45 wt.% Is.
the zinc content in the aluminum-silicon die casting alloy according to the present invention is limited to 0.35 wt% at most, because a higher content greatly reduces the adhesive adhesion when installing such a component and increases the tendency to corrosion. On the other hand, a higher zinc content would advantageously increase the strength further.
the aluminum-silicon diecasting alloy according to the present invention advantageously, depending on the strength level (eg., For very high-strength properties) tin (Sn) and / or cobalt (Co) to those specified maximum levels.
Tin leads to an increase in the number of vacancies after quenching, resulting in an accelerated precipitation kinetics.
the tin and cobalt content should, however, be limited to max. 0.30 wt .-%, otherwise embrittling intermetallic phases occur in cobalt and low-melting microstructural constituents in the case of tin.
V vanadium
Mo molybdenum
Ti titanium
the aluminum-silicon die-casting alloy according to the present invention individually has a maximum of 0.3% by weight, in total not more than 0.5% by weight of impurities, that is to say the aluminum-silicon diecasting alloy is produced from very pure starting materials ,
the requirement for high purity can be met, for example, by the use of pure aluminum from electrolysis or from unmixed aluminum recyclates, e.g. from the construction or packaging industry.
the maximum values of the impurity elements, especially copper (maximum 0.05% by weight), must be adhered to in order to fulfill the desired properties.
annealing and / or aging involves three or more stages, it is advantageous if the total duration of annealing and / or the total duration of thermal aging corresponds substantially to the abovementioned values, i. the time periods given above for the respective stages are proportionally reduced.
a three-stage annealing for example, as a first stage annealing at a temperature in the range of 320 ° C to 380 ° C may be provided (to reduce residual stresses), then a second annealing stage at about 440 ° C and a third annealing stage at about 490 ° C.
a thermal aging at a temperature in the range of 240 ° C to 300 ° C for a short period of time in the range of about 5 minutes to about 45 minutes be provided (to increase the ductility).
the present invention also encompasses a body component, in particular for a motor vehicle, which is characterized in that it at least partially consists of a die-cast component which has been produced using the method according to the invention or one of its advantageous developments or refinements.
the die cast component of the body component may advantageously have a wall thickness in the range of 0.6 mm to 10 mm. Furthermore, in the case of the body component, the die cast component can be glued to at least one sheet metal component, sheet steel component, aluminum component or cast component.
the body component may be formed, for example, in the form of a strut mount, a longitudinal member, a connecting part, a seat receptacle, a hinge receptacle or a baffle plate.
novel aluminum-silicon die-casting alloy in combination with the inventively provided heat treatment unexpected advantages can be achieved.
a two-stage or multi-stage solution annealing allows the annealing of a component at temperatures of 460 ° C. to 520 ° C. (for example above 480 ° C., preferably above 490 ° C., particularly preferably above 500 ° C.) for a short time of 5 minutes to 35 minutes (eg in the range of 5 minutes to 25 minutes) in the last stage.
the strength level can be adjusted according to the invention on the Abschreckgradienten after the solution annealing.
the relationship is that the higher the quench gradient is chosen, the higher the strength to be achieved.
a two- or multi-stage outsourcing allows the reduction of the aging time by means of separation of the removal mechanisms (nucleation, germ growth, etc.). Surprisingly, it has been shown that especially the second stage has a positive effect on the strength / ductility ratio at the indicated contents of zinc and zirconium.
the second aging stage is designed so that the temperature is higher than in the first Auslagerungsease and is in the range of 195 to 300 ° C.
Comparative examples 1 to 5 do not use an aluminum-silicon die casting alloy according to the present invention
comparative example 6 an aluminum-silicon die casting alloy according to the present invention is treated with only one-step solution heat treatment and single-stage thermal aging
examples 1 to 3 are examples in which aluminum-silicon die cast alloys according to the present invention were subjected to a heat treatment according to the present invention.
the specified time periods during the solution annealing and hot aging correspond to the furnace times.
the components can be transported, for example, either with the aid of a multi-chamber furnace into the chamber at the respectively indicated temperatures or heated by means of ramp heating from a first temperature to a second temperature.
the quenching is done without specifying a lower limit temperature and it was regularly cooled to about room temperature or slightly above, but at least to less than 200 ° C.
Table 1 shows the alloys used and the heat treatment carried out in each case.

the strength values were weighted after prioritization in the body shop (Rm: simple, Rp 0.2 : three times). The averaged strength value is multiplied by the corresponding strain (Rm: single, Rp 0.2 : triply) by the elongation at break A5 and divided by the divisor 100 for reasons of clarity.
Fig. 1 the dependence of the adhesive adhesion (tensile shear strength) in the immersion test after 2 and 4 weeks of the zinc content is shown.
Fig. 2 the dependence of adhesive adhesion (tensile shear strength) in the immersion test is plotted after 2 and 4 weeks depending on the copper content.
the alloys investigated according to these figures respectively correspond to Example 1.
Alloys No. 4 and No. 5 have particularly good mechanical properties at quench gradients> 3 K / s, in particular> 4 K / s.
Typical tensile shear strength values after 4 weeks Immersionstest are about 25 MPa. Very good results are between 27-30 MPa, poor values have tensile shear strengths ⁇ 23 MPa. The results were then normalized to alloy no. 1 (reference alloy).
a particular advantage of the present invention is that aluminum-silicon die-cast alloys are provided by which castings can be obtained that stick through the vehicle body can be connected to each other. Compared to previously known alloys, the alloy according to the invention has a significantly increased adhesive adhesion at a high level of strength.
body components die-cast components in the wall thickness range in the range of ⁇ 1.0 mm and 10 mm wall thickness can be produced, particularly advantageous also very thin-walled components.
wall thicknesses of ⁇ 1.0 mm to a minimum of 0.6 mm are possible by the present invention.
strut mountings As some non-exhaustive examples of body components that can be produced by the present invention, mention may be made of strut mountings, side members, connecting parts, seat mounts, hinge mounts and / or baffle plates.
