Definitions
- the invention relates to an aluminum alloy, the use of a
- Aluminum alloy strip or sheet and a method of producing an aluminum alloy strip or sheet.
- Aluminum magnesium (AlMg) alloys of type 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 by a particularly high strength, with increasing
- Alloys are AlMg2Mn (5049) - AlMg3Mn (5454) or AlMg3.5Mn (5918) aluminum alloys. The constant need for additional
- Weight reduction requires aluminum alloys with higher strengths and thus with a correspondingly higher magnesium (Mg) held in order to provide the desired strength.
- Mg magnesium
- the problem with AlMgMn aluminum alloys with Mg contents of more than 2.4% by weight is that they are increasingly prone to intergranular corrosion when exposed to elevated temperatures for longer times.
- M n has found that in AlMgMn aluminum alloys containing more than 2.4% by weight of magnesium at temperatures of 70 to 200 ° C., ⁇ -Alr precipitate Mg3 phases along the grain boundaries. If the
- German Laid-Open Application DE 102 31 437 A1 proposes to significantly reduce the susceptibility to intergranular corrosion by a specific aluminum alloy composition even after sensitization by heat. She proposes the following
- the present invention has the object to provide an aluminum alloy is available, which has only a low tendency to intergranular corrosion, ie in the ASTM G67 test a mass loss value ⁇ 15 mg / cm 2 , at the same time high strength and good formability provides and Contains standard alloy components, so that the recycling of
- Aluminum alloy is simplified. In addition, a use of the aluminum alloy and a method for the production of products of the aluminum alloy to be proposed.
- the above-described object for an aluminum alloy is achieved in that it
- alloy components which have the following composition in wt .-%:
- Composition is based on the finding that the alloying components Zn, Cr, Cu and Mn with magnesium contents of at least 2.91 wt .-% suppressed the excretion of ß-AlsMg3 particles by the presence of these
- Alloy component Zinc for example, can be used to compensate for 2, 3 times the amount of magnesium above 2.91 wt .-% Mg, so that the resulting aluminum alloy shows only a very low tendency to intergranular corrosion.
- the efficiency of suppressing the intercrystalline corrosion or the precipitation of ⁇ -phases decreases with the alloying components chromium, copper and manganese.
- aluminum alloys can be provided in any case, which have relatively high magnesium contents and thus show higher strengths without these tend to intercrystalline corrosion after exposure to temperature. Higher strengths at comparable
- Corrosion resistance is achieved at a Mg content of at least 3.0 wt .-%.
- Aluminum alloy for example, when casting and rolling in purchasing, it is according to a first embodiment of the invention
- Aluminum alloy advantageous that for the alloy components Zn, Cr, Cu and
- the alloying component Cu has the following content in% by weight:
- an aluminum alloy which is further optimized with respect to the addition of alloy components and which is resistant to intergranular corrosion is characterized provided that the alloying components Mg and Zn have the following contents in% by weight:
- the reduction of the upper limit of the magnesium content allows a further reduction of the maximum zinc concentration, so that a cost-optimized aluminum alloy with very high resistance to intergranular corrosion can be provided.
- the aluminum alloy according to the invention can be further optimized with respect to its strength by virtue of the content of the alloying component Mg being at least 3.6% by weight and not more than 4.5% by weight.
- the increased magnesium levels cause a significant increase in
- the Mg content is limited to a maximum of 4.0 wt .-% in order to improve the corrosion behavior.
- Aluminum alloys characterized in that they also have a very good resistance to intergranular corrosion in addition to a very good strength and formability.
- the object indicated above is achieved according to a further teaching of the invention by the use of an aluminum alloy strip or sheet from an aluminum alloy for producing chassis and structural components in vehicle, aircraft or shipbuilding. Chassis and structural components of vehicles, automobiles or aircraft are frequently exposed to heat sources, for example the exhaust gases of the internal combustion engine or other heat sources, so that aluminum alloys which tend to undergo intercrystalline corrosion after a heat treatment can not normally be used here.
- heat sources for example the exhaust gases of the internal combustion engine or other heat sources
- the higher strength aluminum bands or sheets allow the reduction of wall thickness due to the increased strength. In this respect, they contribute to the further weight reduction of vehicles, ships or even aircraft.
- an aluminum alloy strip or sheet is used consisting of the aluminum alloy according to the invention for producing a chassis and structural part, which is arranged in the region of the engine, the exhaust system or other heat sources of a motor vehicle.
- a typical example of this is a spring or wishbone of a motor vehicle. Areas of this component, especially if they are located close to the engine, are permanently exposed to increased heat input.
- tapes and sheets of erfindunmultien aluminum alloy new applications which are characterized by an increased heat input.
- Welds are generally areas in which heat has entered the metal. This heat input can lead to intercrystalline corrosion, if the aluminum alloy tends to. In the aluminum alloys according to the invention On the other hand, the beta-phase precipitate responsible for the intercrystalline corrosion is largely suppressed, so that the component can be easily welded and yet it does not tend to intergranular corrosion.
- Wall thickness of the aluminum alloy strip or sheet 0.5 mm to 8 mm, optionally 1, 5 to 5 mm. These wall thicknesses are very suitable for a
- Hot rolling temperatures of 280 ° C to 500 ° C
- Aluminum alloy no specific heat treatment step, for example, a solution annealing step at the end of the manufacturing process, but the
- Table 1 shows the chemical analyzes of the standard alloys ST 5049, ST 5454 and ST 5918 and the aluminum alloys VI, V2, V3 and V4 according to the invention.
- Table 1 the value for the by
- the minimum compensation is the value of the "compensated" Mg content, which must be compensated for at least by the alloying components Zn, Cr, Cu and Mn.
- the value given in Table 1 therefore corresponds to the Mg content of the respective aluminum alloys.
- Magnesium content of at least 2.91 wt .-% is relevant, this value is not registered for the standard alloy ST 5049.
- the other standard alloys ST 5454 and ST 5918 have a Mg compensation value which is below the magnesium content of the alloy. As is known, these alloys tend to intergranular corrosion under certain conditions. The reason is considered that the Mg content of these aluminum alloys is not sufficiently compensated. The situation is different with the invention
- Roll ingots were cast from all seven aluminum alloys and the ingots were cast at temperatures of 500 to 550 ° C for at least two hours homogenized.
- the billets thus produced were hot rolled to hot strip at hot rolling temperatures of 280 ° C to 500 ° C and then cold rolled to final thickness, with intermediate annealing and final annealing of the cold strip at temperatures between 300 and 400 ° C in a batch oven.
- the strip thickness was 1.5 mm.
- Sheets were removed from the strips produced and their mechanical properties were determined in a tensile test according to DIN EN 10002-1 perpendicular to the rolling direction. The measured values are shown in Table 2. They show that
- Inventive embodiment VI for example, has a significantly higher tensile strength and yield strength than the standard alloy ST 5049.
- the alloy variant V2 also provides a higher tensile strength and a higher yield strength compared to the standard alloy ST 5454.
- the uniform elongation A g and the strain Asomm arise also for the
- Aluminum alloys according to the invention have very good mechanical properties and can be processed identically to the comparable standard alloys.
- Mass loss measurement according to ASTM G67 subjected to a pretreatment in the form of storage at elevated temperatures.
- the samples were stored for 17, 100 and 500 hours at 130 ° C and then subjected to the mass loss test.
- a storage for 100 hours at 100 ° C was performed to the comparability of the invention
- the standard alloy ST 5049 which has a relatively low magnesium content of 2.05% by weight, has the highest resistance to intergranular corrosion. Even with storage of 500 hours at 130 ° C, this aluminum alloy does not change its corrosion behavior in the test. On the other hand, it also has the lowest mechanical strength values. On the other hand, the standard alloy ST 5454 and the others behave differently
- Standard alloy ST 5918 The ST 5454 has a mass loss of 16.2 mg / cm 2 at 500 hours pre-sensitization at 130 ° C.
- the mass loss of the ST 5918 also shows a very significant increase in mass loss after storage in samples stored for 100 hours or 500 hours at 130 ° C
- the aluminum alloy according to the invention is distinguished by excellent resistance to intergranular corrosion.
