Definitions
- the invention relates to a hardenable aluminum alloy based on Al-Mg-Si.
- WO2013 / 124472A1 suggests adding to the solid solution of the aluminum alloy a vacancy active trace element, tin (Sn) and / or indium (In ), admit.
- main and minor alloying elements can not be arbitrarily varied in their content in the aluminum alloy, because in addition to one desirable high heat-curing ability, other mechanical and / or chemical requirements - such as formability, strength, ductility and / or corrosion resistance - are met. This requires, for example, high concentrations of main alloying elements in the aluminum alloy in order to form certain hot excretions.
- the aluminum alloy should be particularly suitable for the use of secondary aluminum.
- the invention solves the stated object in that the aluminum alloy of 0.6 to 1 wt .-% magnesium (Mg), from 0.2 to 0.7 wt .-% silicon (Si), from 0.1 6 to 0 , 7 wt .-% iron (Fe), from 0.05 to 0.4 wt .-% copper (Cu), at most 0.15 wt .-% (or from 0 to 0.15 wt .-%) Manganese (Mn), at most 0.35 wt .-% (or from 0 to 0.35 wt .-%) chromium (Cr), at most 0.2 wt .-% (or from 0 to 0.2 wt Zirconium (Zr), at most 0.25% by weight (or from 0 to 0.25% by weight) zinc (Zn), at most 0.15% by weight (or from 0 to 0.15% by weight) of titanium (Ti), 0.005 to 0.075% by weight.
- Mg magnesium
- Si silicon
- Si
- Tin (Sn) and / or indium (In) and balance aluminum and production-related unavoidable impurities, wherein the ratio of the weight percent of Si / Fe is less than 2.5 and the content of Si according to the equation wt .-% Si A + [0.3 * (wt% Fe)] with the parameter A ranging from 0.17 to 0.4% by weight.
- An aluminum alloy tuned so closely in Si and Fe content which tuning can be recognized, for example, in the shaded area in FIG. 1, can in fact be due to the upper limit of said provision for sufficient solubility of tin and / or indium in the solid solution
- Aluminum alloy ensure that slows down the excretion behavior during cold curing and thus the storage stability of the aluminum alloy is beneficial.
- a sufficient precipitation behavior in the thermosetting is to be expected - whereby high strength values can be achieved in the thermosetting and the aluminum alloy itself can achieve or improve those mechanical and chemical properties of 6xxx aluminum alloy with a higher content of main and Secondary alloy elements are known.
- the advantages of a particularly high storage stability at room temperature and good heat-setting ability of the aluminum alloy can be combined.
- composition of the invention can also be particularly suitable for the use of secondary aluminum for this purpose due to the comparatively high Fe content.
- impurities each having a maximum of 0.05 wt% and a total of at most 0.15 wt% may occur.
- maximum weight percentages such as those found with Mn, Cr, Zr, Zn or titanium, for example, can be considered as starting from 0.
- the storage stability and the thermosetting ability of the aluminum alloy can be further improved when the parameter A is in the range of 0.26 to 0.34 wt%.
- the solubility of Sn can be relatively large and Si exercise only a small impact on cold curing. This allows an unexpectedly high stability at room temperature.
- this alloy set in this way can attain surprisingly high strength after hot curing, for example by means of heat aging, although this alloy has a comparatively low Si content.
- the ratio of the weight percent of Si / Fe is less than 2, by increasing the setting of Si by Fe, the content of dissolved Si in the aluminum alloy can be significantly reduced.
- the solubility of tin and / or indium in the solid solution of the Al-Mg-Si-aluminum alloy can be improved, which can further increase the storage stability.
- a comparatively high solubility of tin and / or indium in the solid solution of the Al-Mg-Si-aluminum alloy can be achieved when the ratio of the weight percent of Si / Mg is in the range of 0.3 to 0.9.
- the aluminum alloy has at least 0.25% by weight of copper (Cu), on the basis of this comparatively high content of Cu, it can compensate for the adverse effects of Mg and Si on the solubility of Sn in the solid solution of Al-Mg-Si Aluminum alloy are intervened.
- Cu copper
- solid solution may denote a state in which an alloying element is distributed in a solid matrix.
- the aluminum alloy belongs to the 6xxx series.
- the aluminum alloy is an EN AW-6061 aluminum alloy. If the aluminum alloy has at most 0.05% by weight of chromium (Cr) and more than 0.05% by weight of zirconium (Zr), the quenching sensitivity for Sn can be reduced and Sn can be kept in solid solution in the mixed aluminum crystal even at comparatively low quenching rates become. In addition, it is thus possible, even with heavy plates, to achieve optimum storage stability and heat-hardening capability.
- the aluminum alloy may have at least 0.02 wt% chromium (Cr) to eventually improve the corrosion performance.
- the aluminum alloy 1 of Table 1 essentially corresponds to a standard alloy AA6061 after addition of the trace element Sn, it being conceivable instead of tin to use indium or a combination of Sn and In.
- Alloy 2 represents the composition according to the invention of the 6xxx series and is relatively recycling-friendly due to the comparatively high Fe content.
- the aluminum alloy 1 is significantly outside the inventively tuned Si / Fe content, we can see this for example in FIG. 1.
- the Aluminum alloy 2 is placed substantially centrally in this tuned Si / Fe content.
- Both aluminum alloys 1 and 2 were solution-annealed in solid solution, quenched, and cold-cured by aging at room temperature and then thermoset. Solution heat treatment was carried out at a temperature greater than 530 degrees Celsius - quenching at a quench rate greater than 20 degrees Celsius / second. Both alloys 1 and 2 were subjected to a storage time or cold curing of 180 days [d] and a 30-minute thermosetting at different temperatures. Brinell hardness [HBW] was determined during cold aging and after hot aging.
- the alloy 1 undergoes a comparatively rapidly increasing cold hardening during storage at room temperature after only 14 days - which leads disadvantageously to a comparatively high and increasing Brinell hardness over a longer storage time and is disadvantageous reshape before hot curing.
- alloy 2 In contrast, in the case of alloy 2, initial cold hardening does not become apparent until after about 180 days, as a result of which alloy 2 according to the invention is considered to be particularly stable in storage. Such a surprisingly high storage stability has not yet been observed with any 6xxx alloy. This leads to an unexpected, enormous gain in the manipulation time of the alloy after quenching in the soft state.
