Definitions

  • the invention relates to a method for producing a structural component made of an aluminum alloy by die casting.
  • WO-A-96/10099 are cast aluminum alloys with an additive known from Scandium to increase strength The high strength results warm aging after solution annealing and quenching with Water.
  • the present invention makes use of the knowledge that scandium and zirconium largely remain in supersaturated solution when cooled rapidly and lead to finely dispersed, submicron precipitates at temperatures in the range between approximately 230 and 350 ° C.
  • the strength of the base alloy can be increased by precipitation hardening.
  • Scandium can be partially replaced by zirconium; a combination of both elements leads to the favorable curing effect according to the invention due to the formation of the isomorphic phases Al 3 Sc and Al 3 Zr, both of which are characterized as face-centered cubic superstructure phases in the Al matrix lattice.
  • the alloy in the first alloy system (AlMnFe), preferably consists of 0.15 to 0.25 % By weight silicon 0.5 to 0.7 Wt% iron 1.2 to 1.4 Wt% manganese Max. 1.5 % By weight magnesium Max. 0.3 % By weight titanium Max. 0.1 % By weight zinc 0.05 to 0.2 % By weight of scandium optionally still 0.1 to 0.2 % By weight of zirconium as well as aluminum as the rest with further impurities individually max. 0.02% by weight, max. 0.2% by weight.
  • the alloy preferably consists of 0.15 to 0.25 % By weight silicon 0.05 to 0.15 Wt% iron 0.8 to 1.0 Wt% manganese 2.5 to 3.5 % By weight magnesium Max. 0.2 % By weight titanium Max. 0.1 % By weight zinc 0.05 to 0.2 % By weight of scandium optionally still 0.1 to 0.2 % By weight of zirconium as well as aluminum as the rest with further impurities individually max. 0.02% by weight, max. 0.2% by weight.
  • the strength-increasing effect of the scandium additive results in one small part already during the actual die casting process.
  • a substantial increase in strength can be achieved by a subsequent Heat treatment in a temperature range of 230 to 350 ° C reached become.
  • By choosing the appropriate temperature and duration of the heat treatment can be a desired optimum between high ductility and Strength can be adjusted.
  • the alloys are therefore Particularly suitable for the production of structural components that act as safety components in vehicle construction and in particular in automobile construction, for example as space frame nodes or as crash elements.
  • the Structural components are particularly suitable for applications in which one Temperature load occurs up to about 180 ° C.
  • alloy Composition (% by weight) Si Fe Mn mg Zr Ti sc 1 00:10 00:10 1.2 3.2 0016 00:15 2 0043 0077 1:32 00:01 0089 0099 00:14
  • a die-cast part was produced from alloy 1. Alloy 2 was cast into plates with a thickness of 3 mm to simulate the cooling during die-casting. Test rods for tensile tests were worked out from the cast parts and the mechanical properties in the cast state with and without subsequent heat treatment were measured on them. The results are summarized in Table 2.
  • Rp 0.2 means the yield strength
  • Rm the tensile strength
  • A5 the elongation at break.
  • alloy heat treatment Mechanical properties
