Definitions
- the invention relates to an aluminum alloy, in particular an aluminum alloy, which in addition to aluminum magnesium and silicon as main alloying constituents and is intended for use in die casting and related processes.
- Aluminum die casting parts have become particularly important in the automotive industry.
- an aluminum alloy having> 3.0 to 7.0 wt% of magnesium, 1.0 to 3.0 wt% of silicon, 0.3 to 0.49 wt% of manganese, 0.1 to 0 , 3% by weight of chromium, 0 to 0.15% by weight of titanium, max. 0.15 wt .-% iron and each max. 0.00005% by weight of calcium and sodium and max. 0.0002 wt .-% phosphorus known.
- an alloy which contains 3.0 to 6.0, preferably 4.6 to 5.8,% by weight of magnesium, 1.4 to 3.5, preferably 2.0 to 2.8,% by weight of silicon, 0.5 to 2.0, preferably 0.6 to 1.5 wt .-% manganese, max. 0.2, preferably 0.1 to 0.2 wt .-% titanium and max. 0.15, preferably max. Contains 0.1 wt .-% iron and is already in Rheoge Stahl.
- AlMgSi alloys are intended for use in die casting and related processes. Already in the as-cast state they have similar strength and elongation values as AlSiMg alloys, eg the well-known AlSi7Mg0.3 alloy, in the fully cured state (which is referred to as "T6").
- the 0.2% proof strength characterizes the transition from the elastic to the plastic deformation of a casting and is particularly relevant in connection with crash-relevant structural parts in the automotive industry.
- heat treatment of die-cast parts of the above-mentioned AlMgSi alloys involves numerous disadvantages.
- this eliminates the cost advantage that can be achieved by such alloys.
- Other significant disadvantages of the heat treatment are typical defects in die cast parts such as distortion and especially bubbles, which are caused by thermal destruction of trapped mold release agents and are known by the term "blister".
- blister a delay nullifies the process advantage of die-cast parts, namely the near-end production.
- AT 412 726 shows an aluminum alloy containing, by weight, 0.3 to 4.5% Si, 1.0 to 8.0% Mg, 0.05 to 0.5% Sc, less than 0.7% Fe, less as 0.2% Zn and Cu, optionally one or more elements selected from the group 0.01 to 1.0% Mn, 0.01 to 1.0% Cr, 0.01 to 1.0% Ni, 0, 01 to 0.3% Ce, 0.01 to 0.3% La and further optional secondary alloying elements.
- the alloy should be able to produce components close to the final dimensions by casting and have high mechanical strength values or be heat treatable.
- the WO 00/43560 discloses an AlMgSi alloy which, by weight, contains 2.5 to 7% Mg, 1.0 to 3.0% Si, 0.3 to 0.49% Mn, 0.1 to 0.3% Cr , 0 to 0.15% Ti, max. 0.15% Fe, max. 0.00005% Ca, max. 0.00005% Na, max. 0.0002% P, other impurities in an amount of max. 0.02% and the remainder being Al and optionally 0.05 to 0.02% Zr.
- the alloy should have good mechanical properties in the cast state, especially a high ductility. Z. Yin et al., "Effect of minor Sc and Zr on the microstructure and mechanical properties of Al-Mg based alloys", Materials Science and Engineering, Vol.
- the object of the present invention is therefore to provide aluminum alloys of the AlMgSi type which are suitable for use in diecasting and have comparable strength properties compared to the alloys known from the prior art, but higher values with regard to the 0.2% proof stress .
- Another object of the invention is to provide such aluminum alloys, which have the desired strength properties already in the cast state, so that a heat treatment of die castings and the associated disadvantages are avoided.
- a zirconium content of 0.05 to 0.2 wt .-% is provided.
- the rare earth metals samarium, cerium or lanthanum can be alloyed alone or in any combination. Particularly advantageous are combinations of samarium and cerium or samariam and lanthanum.
- a particularly preferred alloy contains the rare earth metals samarium and cerium in an amount of 0.0050 to 0.8% by weight of samarium and 0.0050 to 0.8% by weight of cerium.
- cerium also reduces the sticking tendency of the alloy in the diecasting tool, which additionally has an advantageous effect on the quality of the diecasting parts.
- the present invention will be further illustrated with reference to the mechanical characteristics determined for the following alloys.
- the mechanical characteristics were determined on step plates produced by die casting in the tensile test according to DIN EN 10002, wherein the 2.7 mm step was used for the tensile test.
- This wall thickness range is preferably used for the production of weldable and possibly crashrelevanten structural parts.
- the mechanical characteristics represent the average of 25 measurements.
- the results of the tensile tests performed are shown in Table 1.
- the reference alloy is an alloy whose composition corresponds to an alloy according to the invention, but does not contain any alloying with rare earth metals.
- the strength values achievable with the aluminum alloys according to the invention are also at a level which is achieved with forgings made of AlSi1MgMn in the state T6, that is to say after a heat treatment. Because of this and the improved compared to the known aluminum alloys of AlMgSi-type 0.2% proof strength alloys of the invention for new applications, in particular for the production of highly loaded aluminum die cast parts, as they are increasingly of interest in the automotive industry, suitable.
- the aluminum alloy according to the invention is used for the die casting, squeeze casting, thixoforming or thixoforging process and other processes which are based on shaping in the partially liquid state.
