Definitions

  • the invention relates to a method for producing a component with high Ductility requirements from an aluminum alloy by die casting. in the An application of the method as well as a Use of a component manufactured using the method.
  • the die-casting process enables the cost-effective production of large quantities Manufacture of thin-walled castings, such as those used in crash-relevant components Automotive engineering can be used.
  • Thin-walled parts place high demands of the castability.
  • Aluminum alloys that adhere to the flow behavior or mold filling requirements, are mainly alloys with a Si eutectic.
  • Suitable alloy based on aluminum-silicon is from EP-B-0687742 known.
  • the alloy corresponds to the type AlSi9Mg with considerable reduced iron content and strontium refinement of the AlSi eutectic.
  • the alloy becomes complete before heat treatment is carried out solution annealed and then quenched.
  • the invention is therefore based on the object of an aluminum alloy specify a heat treatment with which a high elongation at break sufficient yield strength even without high-temperature annealing can be achieved with subsequent water quenching.
  • the alloy essentially corresponds to the alloy known from EP-B-0687742 with an increased iron and reduced manganese content.
  • This variation in the alloy composition has a positive influence on the mechanical properties, since the Al 12 (Mg, Fe) Si 2 phases are significantly finer and more evenly distributed, which ultimately results in improved ductility. Due to the higher iron content, aluminum of lower purity can be used as an alloy base, which reduces the cost of the alloy. In addition, the higher iron content makes it possible to reduce the manganese additive used to reduce the tendency of the alloy to stick in the die.
  • the temperature range and duration of the solution annealing are thus chosen so that on the one hand the strong cast oversaturation of Silicon is broken down to improve the ductility and on the other hand the Yield strength through subsequent heat curing to the required Values can be set.
  • the temperature range for the partial solution treatment is preferably between about 420 and 460 ° C. Accepting a minor mechanical The component can lose strength for certain applications without subsequent Hot curing can be used.
  • the component can also be heat-cured after the partial solution annealing in the temperature range of the precipitation hardening of Mg 2 Si.
  • This heat curing is preferably carried out in a temperature range from approximately 190 to 220 ° C.
  • the preferred field of application of the method according to the invention is in the production of large-area and thin-walled components with high absorption capacity for kinetic energy through plastic deformation, i.e. crash-relevant components such as safety components in vehicle construction and be used in particular in the automotive industry.
  • crash-relevant components such as safety components in vehicle construction and be used in particular in the automotive industry.
  • safety components are space frame nodes and crash elements.
  • alloy B is a comparative alloy and corresponds to an alloy according to EP-B-0687742.
  • alloy Composition (% by weight) Si Mn Fe Mg Ti Sr.
  • A 10.45 0.45 0.24 0.28 0.05 0.014
  • B 10.88 0.58 0.10 0.17 0.05 0.013
  • Alloys A and B became the same, difficult to cast Component manufactured with a vacuum die casting process.
  • the component is a so-called "B-pillar" for vehicle construction, i.e. on large-area and thin-walled component with a wall thickness of 2 mm.
  • the component made from alloy A according to the invention was subjected to the following heat treatment after casting: Partial solution annealing 440 ° C / 60 min in air Cooling in still air Hot aging 220 ° C / 110 min in air
  • the distortion was measured on a component made from alloy A according to the invention after various heat treatments.
  • the distortion was determined as follows: A reference point (zero point) was defined on the cast part in the cast state (ie before the heat treatment) at a certain point. After the heat treatment, the distance to the reference point was then measured. This distance defines the distortion as a measure of the deformation that arises due to the heat treatment carried out.
  • Table 2 Heat treatment / cooling Solution annealing 493 ° C / 60 min water quenching part. Solution annealing 440 ° C / 60 min cooling in still air part. Solution annealing 440 ° C / 60 min cooling with fan Delay (mm) 6.5 ⁇ 0.5 ⁇ 0.5
  • alloy A according to the invention The components made from alloy A according to the invention and comparative alloy B were heat-treated as follows after casting: Partial solution annealing 420 ° C / 20 min Cooling in still air
  • Table 3 clearly shows the improved elongation at break values of alloy A according to the invention compared to comparative alloy B.
  • This improved ductility of alloy A according to the invention becomes the positive influence of the higher iron content and consequently the finer formation and more uniform distribution of Al 12 (Mn, Fe) Si 2 Phases in the alloy A according to the invention compared to the comparative alloy B.
  • the different formation and distribution of the brittle Al 12 (Mn, Fe) Si 2 phases could be confirmed metallographically using micrographs.
  • Orientative tests have further shown that even when the iron content is increased to 0.35% by weight and the manganese content is simultaneously reduced to 0.4% by weight, no ⁇ -AlFeSi phases harmful to the ductility occur.
  • Corrosion tests have also shown that pitting corrosion observed with small iron contents due to the rough precipitation of the Al 12 (Mn, Fe) Si phases, which act as cathodic local elements, is prevented by the increased iron content.
