Definitions

  • the invention relates to a diecasting alloy based on aluminum and silicon, in particular for use in light vehicle structural parts.
  • the alloy according to the invention takes account of the ever increasing demands for lightweight construction in the automotive industry.
  • the use of a material with higher strength allows the designer to realize thinner-walled and thus lighter structures. In this way, a further step towards low fuel consumption in the automobile can be realized.
  • AISi10Mg or AISi7Mg alloys are among the most widely used casting alloys in the industry.
  • the EP 1612286 B1 discloses an AISi alloy which already exhibits high elongation values in the cast state without further heat treatment. With this alloy it is possible to obtain good values for the yield strength and the tensile strength of castings as cast, so that the alloy is particularly suitable for the production of safety components in the automotive industry. In this known from the prior art alloy has been shown that by the addition of molybdenum or a combined addition of molybdenum and zirconium, the desired values for the tensile strength and the yield strength can be achieved.
  • the EP0687742B1 also discloses an aluminum-silicon based die-casting alloy, which is used in particular in automotive safety components. Unlike the alloy from the EP 1612286 B1 , the produced die castings are subjected to a heat treatment. In the case of this alloy, it has been found that the achieved increased strength values depend to a large extent on the magnesium content and this content therefore has to be tolerated very closely in the production.
  • the object of the invention is to develop a high-strength die-cast aluminum alloy which exhibits improved mechanical properties in terms of tensile strength, yield strength and elongation at break.
  • the alloy according to the invention is said to have good castability, no increased tendency to adhere, no increased risk of heat cracking, and no restriction as regards mold filling capability.
  • the aluminum base may contain at least 50% secondary metal (recycled material).
  • the alloy according to the invention contains 0.15-0.5% by weight of iron.
  • the alloy according to the invention contains 0.05 to 0.20% by weight of molybdenum.
  • the alloy according to the invention contains from 0.05 to 0.20% by weight of zirconium.
  • the alloy according to the invention contains 0.3 to 0.5% by weight of manganese.
  • the alloy according to the invention contains 0.2 to 0.4% by weight of zinc.
  • the alloy according to the invention contains 0.15 to 0.25% by weight of copper.
  • the alloy according to the invention contains 8.5 to 10.0% by weight of silicon.
  • the alloy according to the invention contains from 0.3 to 0.4% by weight of magnesium.
  • the diecasting alloy according to the invention is preferably used for pressure casting of crash-relevant or strength-relevant structural parts in the automotive industry.
  • the appropriate strength of an aluminum die casting alloy is achieved in addition to the choice of combination of alloying elements by a targeted heat treatment.
  • the alloy according to the invention is subjected to a T6 heat treatment comprising solution heat treatment, air quenching or water quenching and heat aging. It could be determined that compared with the alloy EP 0687742B1 high yield strengths of just over 200 N / mm 2 can be achieved.
  • the alloy according to the invention is time-stable after T6 heat treatment, i. there is no self-curing.
  • the alloy according to the invention may be subjected to a T7 heat treatment.
  • alloy composition according to the invention it is possible to achieve improved values for tensile strength, the yield strength and the elongation at break in die cast parts in the material state T6 or T7.
  • the slightly increased iron content is taken into account by a reduction in the manganese content, otherwise there is a risk of sludge formation in the holding furnace at the casting machine.
  • the tendency of the alloy to adhere decreases, since both iron and manganese have a positive effect and the reduction of Mn is more than compensated for by the Fe content.
  • the MnFe ratio prevents the formation of so-called beta phases, ie plate-shaped AlMnFeSi precipitates, which significantly reduces the ductility of the material.
  • Such excretions are known under the microscope as so-called. Iron needles.
  • the alpha-AlMnFeSi precipitates are formed very finely in the inventive alloy by the addition of the elements Mo, Zr and Ga, so that their harmful effect on Dehnhong and corrosion tendency can be minimized.
  • strontium or sodium leads to a finely crystalline precipitation of the silicon, which results in the formation of a refined eutectic, and also has a positive influence on the strength and elongation of the inventive alloy.
  • Grain refining is preferably carried out in the case of the alloy according to the invention.
  • the alloy may preferably be supplied with 1 to 30 ppm of phosphorus.
  • the alloy may also contain titanium and boron for grain refining, the addition of titanium and boron via a master alloy with 1 to 2% by weight of Ti and 1 to 2% by weight of B, residual aluminum.
  • the aluminum master alloy contains 1.3 to 1.8% by weight of Ti and 1.3 to 1.8% by weight of B, and has a Ti / B weight ratio of about 0.8 to 1.2.
  • Of the Content of the master alloy in the alloy according to the invention is preferably adjusted to 0.05 to 0.5 wt .-%.
  • the weldability could be checked in TIG welding tests.
  • punch rivet tests the alloy according to the invention was rivet free of cracks despite its high strength.
  • compositions of an exemplary alloy of the EP0687742B1 (Alloy 1) and two embodiments (alloys A, B) of the inventive alloy compared.
  • the statements are in wt .-%.
  • the mechanical characteristics (R m , R p0.2 and A 5 ) were measured on 3 mm die-cast plates.
  • the same T6 heat treatment with air quenching and applied with water quenching The mean value of approx. 30 train tests is shown in each case.
