Definitions

  • the invention relates to a component made of an alloy of the AlMgSi type, with a high absorption capacity for kinetic energy through plastic deformation.
  • the aluminum materials that are processed into crash elements today include standard alloys from AlMgSi. Although alloys of this type have good preconditions for energy-absorbing parts compared to other alloy systems such as AlZnMg in terms of their elongation and formability, a further optimization of the properties is desirable.
  • the invention is therefore based on the object, suitable To provide materials with particularly good deformability and good mechanical properties of the component.
  • the alloy in% by weight silicon 0.3 to 1.6 magnesium 0.3 to 1.3 iron Max. 0.5 copper Max. 0.9 manganese Max. 0.5 Vanadium 0.05 to 0.3 cobalt Max. 0.3 chrome Max. 0.3 nickel Max. 0.8 Zircon Max. 0.3 as well as further alloy elements individually max. 0.05, total max. 0.15 and aluminum as the rest.
  • vanadium according to the invention leads to a fine-grained structure with excellent deformation properties and good elongation even in the transverse direction.
  • the alloy has 0.08 to 0.13% by weight of vanadium and also contains 0.05 to 0.15% by weight of manganese.
  • alloy composition according to the invention for the production of components with high energy absorption capacity leads to a favorable microstructure of the component structure.
  • An important feature of the microstructure that improves the deformation properties is the smallest possible grain size. This is achieved with the alloy composition according to the invention.
  • a component with particularly good properties with regard to energy absorption with good strength values can be achieved by a special heat treatment. This consists in the generation of an aged or partially hardened state of the alloy, i.e. the alloy is not hardened to maximum strength.
  • the aged condition is produced by annealing in the range between 120 and 170 ° C, the annealing time being in the range between 4 and 16 h.
  • the desired degree of underaging can be determined using a simple series of experiments.
  • the components according to the invention are extruded profiles.
  • components are also conceivable which, starting from an extruded profile as a preform, are finished by hydroforming.
  • the component can also be a forged part.
  • a preferred use of the component according to the invention is seen as a safety part in vehicle construction.
  • the alloy A according to the invention has a significantly lower grain coarsening compared to the comparative alloy B in annealing operations such as, for example, intermediate annealing shows.
