Definitions

  • the invention relates to an aluminum alloy strip consisting of an aluminum alloy of the type AA 5xxx, which in addition to Al and unavoidable impurities has a Mg content of at least 4 wt .-%.
  • the invention relates to a method for producing the aluminum alloy strip according to the invention and a component made from an aluminum alloy strip according to the invention.
  • Aluminum magnesium (AlMg) alloys of type AA 5xxx are used in the form of sheets or plates or strips for the construction of welded or joined structures in shipbuilding, automotive and aircraft construction. They are characterized in particular by a high strength, which increases with increasing magnesium content.
  • Aluminum alloy ribbons of the type AA5182 with a Mg content of at least 4 wt .-% are also from the article Semi-Solid Processing of Alloys and Composites by Kang et al. and from the paper Comparison of recrystallization textures in cold-rolled DC and CC AA 5182 aluminum alloys by Liu et al., as well as from the US 2003/0150587 A1 known.
  • the article Hot-Tear Susceptibility of Aluminum Wrought Alloys and the Effect of Grain Refining by Lin et al. concerns round bars made of his AA5182 alloy.
  • the DE 102 31 437 A1 relates to corrosion-resistant aluminum alloy sheets, whereby the addition of Zn in a content of more than 0.4% by weight affords sufficient resistance to intergranular corrosion.
  • AlMg alloys of the type AA 5xxx with Mg contents of more than 3%, in particular more than 4%, are increasingly prone to intercrystalline corrosion when exposed to elevated temperatures.
  • ⁇ -Al 5 Mg 3 phases separate out along the grain boundaries, which are called ⁇ -particles and can be selectively dissolved in the presence of a corrosive medium.
  • This relates in particular to the components of a motor vehicle, which are usually subjected to a cathodic dip coating (KTL) and then dried in a baking process, since sensitization with respect to intercrystalline corrosion can already be caused by this baking process in conventional aluminum alloy tapes.
  • KTL cathodic dip coating
  • the forming during the production of a component and the subsequent operating load of the component must be taken into account.
  • the susceptibility to intergranular corrosion is usually tested in a standard test according to ASTM G67, in which the samples are exposed to nitric acid and the mass loss due to the release of ⁇ -particles is measured.
  • ASTM G67 the mass loss for materials which are not resistant to intergranular corrosion is more than 15 mg / cm 2 .
  • the object of the present invention is to propose an aluminum alloy strip of an AlMg alloy which, despite high strengths and Mg content of more than 4% by weight, in particular also after deformation and subsequent application of temperature, is resistant to intergranular corrosion .
  • a manufacturing method is to be specified, with which against intergranular corrosion resistant aluminum strips can be produced.
  • intergranular corrosion resistant components of a motor vehicle such as body parts or body parts, such as doors, hoods and tailgates or other structural parts but also component parts of an aluminum alloy type AA 5xxx.
  • Residual Al and unavoidable impurities individually a maximum of 0.05 wt .-%, in total not more than 0.15 wt .-%.
  • An aluminum alloy ribbon having a recrystallized structure may be provided by hot strips or soft annealed cold strips.
  • Extensive research has found that there is a correlation between grain size, magnesium content, and intergranular corrosion resistance. Since the grain size of a material is always in the form of a distribution, all information given the grain size on the average grain size. The mean grain size can be determined according to ASTM E1382. If the grain size is sufficiently large, that is, if the grain size is greater than or equal to the lower limit of the grain size of the present invention, resistance to intergranular corrosion can be achieved, so that mass loss is less than 15 mg in the ASTM G67 test / cm 2 drops. Corresponding aluminum strips can therefore be termed resistant to intergranular corrosion.
  • the aluminum alloy ribbon of the present invention because of its relatively high Mg content, provides high strengths and yield strengths while being resistant to intergranular corrosion. It is therefore very suitable for use in heat-stressed areas in the automotive industry.
  • Residual Al and unavoidable impurities individually a maximum of 0.05 wt .-%, in total not more than 0.15 wt .-%.
  • Mg range to 4.45 wt .-% to 4.8 wt .-% is also a very good strength with a moderate grain size can be achieved.
  • the grain size is a maximum of 50 microns, since in the production of aluminum strips with grain sizes of more than 50 microns from an aluminum alloy of type AA 5xxx with a Mg content of at least 4 wt .-%, the process reliability drops , On the other hand, a grain size of maximum 50 ⁇ m can be achieved with process stability.
  • the process stability for the production of microstructures with controlled grain size increases with decreasing grain size.
  • the production of an aluminum alloy strip having a grain size of not more than 45 ⁇ m, preferably not more than 40 ⁇ m is associated with increasing process stability.
  • this has a thickness of 0.5 mm - 5 mm and is thus outstandingly suitable for most applications, for example in the automotive industry.
  • the aluminum alloy strip according to the invention can advantageously be configured by being cold rolled and finally soft annealed.
  • a recrystallizing soft annealing usually takes place at temperatures of 300 ° C - 500 ° C and makes it possible to eliminate the introduced in the rolling process solidifications and to ensure a good formability of the aluminum alloy strip.
  • cold end, soft annealed and therefore recrystallized tapes can provide lower final thicknesses than recrystallized hot tapes.
  • the aluminum alloy strip has a yield strength R p0.2 of more than 120 MPa and a tensile strength R m of more than 260 MPa.
  • the aluminum alloy strip according to the invention which is resistant to intercrystalline corrosion also exceeds the strength properties of an aluminum alloy of the AA5182 type required in accordance with DIN485-2.
  • the enumerated process steps lead in sum to the fact that due to the small Abwalzgrads in the cold rolling of the aluminum alloy strip to final thickness, a grain size can be provided after annealing, which meets the above-mentioned dependence on the Mg content.
  • the solidification of the strip is set before annealing, which determines the resulting grain size.
  • different grain size can be set, which can be tailored to the alloy composition. In this respect, an aluminum alloy strip which is resistant to intergranular corrosion can be produced.
  • the degree of rolling before soft annealing ie the degree of rolling at the final thickness during cold rolling, is limited to less than 40%, preferably not more than 30%, particularly preferably not more than 25%.
  • an additional cold rolling step after an intermediate annealing at 300 ° C - 500 ° C instead.
  • the aluminum alloy ribbon strongly solidified by the cold rolling is recrystallized and again converted into a workable state.
  • the subsequent cold-rolling step with a degree of reduction of less than 40%, preferably not more than 30%, particularly preferably not more than 25% results in that, in conjunction with the Mg contents of the aluminum alloy used, the particle size can be adjusted in accordance with the claimed ratio.
  • a strip is then produced in the annealed state, which is both resistant to intergranular corrosion and has the necessary forming or strength properties.
  • the soft annealing and / or the intermediate annealing take place in a batch furnace, in particular a chamber furnace or a continuous furnace. Both furnaces lead to the provision of a sufficiently coarse grain structure, which ensures the resistance to intergranular corrosion. Batch ovens are usually not as expensive to operate and purchase as continuous ovens.
  • the above-described object is achieved by a component for a motor vehicle, which at least partially consists of an aluminum alloy strip according to the invention.
  • the component is usually subjected to a coating, preferably a cathodic dip coating. Nevertheless, there are also possible uses of unpainted components made from the aluminum alloy strip according to the invention.
  • the aluminum alloy strip has excellent properties in terms of strength, forming properties and resistance to intergranular corrosion, so that in particular the heat load in a painting, a baking process typically 20 minutes at about 185 ° C takes little effect on the resistance of the component against intergranular corrosion.
  • the transformation to a component which was simulated by means of a stretching by 15% transverse to the original rolling direction, has only a small influence on the resistance to intergranular corrosion.
  • the mass loss values according to ASTM G67 are less than 15 mg / cm 2 .
  • the operation in temperature-stressed areas which was simulated by a heat load of 200 or 500 hours at 80 ° C, only a small effect on the resistance to intergranular corrosion.
  • the mass loss values according to ASTM G67 are less than 15 mg / cm 2 even after a corresponding temperature load.
  • a component if this is designed as a body or a body attachment of a motor vehicle.
  • Typical body parts are the fender or parts of the floor assembly, the roof, etc.
  • body parts usually doors and tailgates etc. are referred to, which are not firmly connected to the motor vehicle.
  • non-visible body parts or body parts are made from the aluminum alloy strip according to the invention. These are, for example, door inner parts or inner parts of tailgates but also floor panels, etc.
  • a typical heat load for such components of a motor vehicle, for example, of door inner parts is given, for example, by the solar radiation during the operation of a motor vehicle.
  • bodywork or bodywork components of a motor vehicle are generally also exposed to moisture, for example in the form of sprayed water or condensation, so that resistance to intergranular corrosion must be required.
  • the body or body parts according to the invention made of an aluminum alloy strip according to the present invention, meet these conditions and also ensure a weight advantage over the steel structures used to date.
