Definitions

the invention relates to an aluminum alloy for the production of semi-finished products or components for motor vehicles, a semifinished product or component made of an aluminum alloy and a method for producing an aluminum strip for semi-finished products or components for motor vehicles.
components such as parts of the chassis or the body structure, made of aluminum materials are used increasingly for the production of motor vehicles.
These are usually made of semi-finished products consisting of aluminum alloys based on an AlMgMn aluminum alloy with Mg contents of 2 to 3.5 wt .-%.
This aluminum alloy ensures sufficiently high strength combined with good resistance to intergranular corrosion, especially in uncoated applications. Since in the manufacture of the chassis and / or structural components existing from said aluminum alloy semi-finished products are usually subjected to several forming steps, there is a desire to extend the forming limits of the semi-finished products, such as aluminum sheets, tubes or profiles.
hot forming processes such as hot hydroforming, hydroforming with hot media, or deep drawing with heated tools, are increasingly being used in the forming operations.
degree of deformation of the aluminum semi-finished products can be significantly increased when using hot forming processes.
the anti-settling processes taking place in hot forming operations have the components or semi-finished products consisting of the AlMgMn aluminum alloys used today less strength than the cold-worked components used previously.
the object of the present invention is to provide an aluminum alloy and a semifinished product or a component which, with good resistance to intergranular corrosion and recyclability, has sufficient strength even after hot working.
the aluminum alloy according to the invention makes it possible to produce components which are not only resistant to intercrystalline corrosion but also have a higher strength after hot working compared with the aluminum alloys used hitherto. Moreover, since the aluminum alloy according to the invention contains only standard alloy components, it is very easy to recycle and can be introduced without problems into the scrap circuits of the automotive industry (Alt-Autover Aunt), as well as the semis manufacturer.
a corresponding aluminum alloy leads to a further increase in the yield strength Rp0.2 at room temperature after hot deformation with constant resistance to intergranular corrosion, while the elongation at break values remain the same.
the object indicated is achieved by a semifinished product or a component which consists at least partially of an aluminum alloy according to the invention.
semifinished products or components consisting of the aluminum alloy according to the invention can be used particularly well for chassis and structural applications in motor vehicles, since they have an improved yield strength at room temperature, in particular after hot forming, with constant corrosion resistance.
a component differs from the semifinished product in that the component has been subjected to further process steps in order to be used, for example, directly in the body of the motor vehicle.
the semifinished product thus represents the starting product for the components.
the possible uses of the semifinished product or component in structural applications in the motor vehicle sector can be increased by forming the semifinished product or component at room temperature or in a soft state at sheet thicknesses of at least 1 mm Yield point Rp0,2 of at least 135 MPa. Due to the high yield strength of the semifinished product or component according to the invention after forming at room temperature or in a soft state, measured according to DIN standard DIN EN 10 002, the necessary requirements for the yield strength Rp0.2 for use as a structural part by the semifinished product or component met in the vehicle.
the suitability of the semifinished product or component for structural applications in the motor vehicle can be further improved in that the semifinished product of hot forming with a degree of deformation of at least 15% and at most 50% to 120% at a temperature of 200 to 350 ° C.
the semifinished product has an elongation at break A 5 of at least 50% in the hot tensile test and that the semifinished product has a yield strength at room temperature Rp0.2 of at least 150 MPa.
the elongation at break values A 5 in the hot tensile test were measured at the respective hot forming temperatures with a corresponding proportional rod.
the yield strength Rp0.2 of the structural parts clearly exceeds the yield strength Rp0.2 from the known AlMgMn aluminum alloy with a Mn content of 2 to 3.5% by weight of produced structural parts after hot forming, without showing any sensitivity to intergranular corrosion.
a semifinished product or component which is further improved with regard to the yield strength at room temperature and the elongation at break can be made available by the semifinished product being subjected to hot forming with a degree of deformation of at least 15% and a maximum of 60%.
90% at a temperature of 250 to 350 ° C has been subjected while having an elongation at break A 5 of at least 60% in the hot tensile test and that the semi-finished product after hot working has a yield strength at room temperature of at least 165 Mpa.
the hot tensile tests were carried out on proportional bars at the hot-forming temperatures mentioned.
the area-related mass loss according to ASTM G 67 after a heat treatment of 17 hours at 130 ° C. is a maximum of 5 mg / cm 2 .
the semi-finished products according to the invention therefore have a particularly good resistance to intergranular corrosion and are particularly suitable for use as or for the production of chassis or structural parts in motor vehicles.
the above-described object is achieved by a method for producing a strip for semi-finished products or components by casting a cast bar or a cast strip from an aluminum alloy according to the invention, hot-rolling the cast bar or, optionally, the cast strip, the hot-rolled strip Cold ingot or the casting belt are cold rolled and the cold rolled strip is fed to a final annealing. Due to the properties of the aluminum alloy according to the invention, it is ensured in the described production method that sheets produced from the strip, despite used hot forming processes, have an improved yield strength at room temperature with constant elongation at break values.
Solidification introduced into the strip by hot rolling can be reduced by subjecting the strip to annealing prior to cold rolling.
the cold rolled strip in this case has only the solidifications introduced by cold rolling into the strip.
the solidifications introduced into the strip by the cold rolling are reduced again by at least one intermediate annealing during cold rolling. All of the aforementioned measures serve to increase the formability in the production of aluminum strip for semi-finished products, without the structural parts produced have too low a yield point.
the aluminum alloy C according to the invention has almost identical elongation at break values as a function of the temperature in the hot tensile test in comparison with the conventional comparative alloys A and B.
the comparative alloy A shows as expected, due to the high magnesium content of 4.5 wt .-%, the largest values for the yield strength after hot working.
the value of the yield strength for the comparative alloy A is about 175 MPa at a hot working temperature of 350 ° C.
Comparative alloy B has only reached a value of 140 MPa for the yield strength Rp0.2 at room temperature at the same hot forming temperature.
the exemplary embodiment of the aluminum alloy according to the invention achieves values of significantly more than 150 MPa. Also in the other measured values, for example at 250 ° C., the values for the measured yield strength of the exemplary embodiment of the aluminum alloy according to the invention clearly exceed those of the comparative alloy B, but below the values for the comparative alloy A.
the comparison alloy A is more susceptible to intercrystalline corrosion due to the higher MG content, so that it is not advantageous, especially in long-term use in chassis or structural application in the motor vehicle.
the aluminum alloy of the present invention can provide an aluminum alloy which, despite improved yield strength after hot working, has good intergranular corrosion resistance and good elongation at break properties during hot working.
