Definitions

  • the invention relates a method for Production of an aluminum component according to claim and a Component produced by a method according to claims 1-8.
  • High strength Cu e.g., Al Mg Si 1 Cu 0.5
  • Zn-containing have heat-treated Al semi-finished and Al forgings Although high static strength values, but is their Breaking strain low. In the case of notch effect (e.g. Rockfall) thus results in a low dynamic Strength.
  • these alloys are vulnerable Corrosion, so that to avoid notch-acting Corrosion scars require expensive corrosion protection is.
  • forged Al chassis parts are always exposed to stone chips (notches) and corrosion, In these areas, only in exceptional cases are Cu / Zn ambience Al materials used.
  • Ductilers or notch-oriented Al Mg Si 1 alloys such as. B. the EN-AW 6082 are indeed because of their very low Cu and Zn content Corrosion resistant, but achieve this Alloys do not have sufficient strength values.
  • German Offenlegungsschriften DE OS 2 103 614 and DE OS 2 213 136 each describe an aluminum-silicon-magnesium Alloy, the recrystallization inhibiting reacts, but these alloys are too low Strength on, also is the tendency to recrystallization this alloy for multi-formed or cold-formed Components still too high. The same goes for the known alloy according to EN-AW 6082.
  • the object of the invention is a component and a method for producing a component to provide better than the prior art recrystallization-inhibiting effect and to a higher Strength and corrosion resistance of the components lead.
  • the solution of the task consists in one Method according to Claim 1 and in a component according to claim 9.
  • the Alloy a silicon content between 0.9 and 1.7 wt.% on.
  • the invention is also characterized by the fact that the Alloy elements manganese, chrome and zirconium and / or Hafnium together account for at least 0.4% by weight exhibit. Preferably, the proportion of these Elements higher than 0.6% by weight. These elements act as Recrystallization inhibitors.
  • the alloy has a silicon content of 0.9 to 1.3% on. It turned out that a lower Silicon content not to the required strength values leads.
  • the silicon works in combination with the magnesium in the form of precipitation hardening (heat treatment), the in the form of Mg2Si precipitates. higher Levels of manganese and chromium also lead to one Precipitation hardening or strengthening.
  • the alloy is particularly resistant to Recrystallization both in hot working and in Cold forming. It is almost independent of a high strength and a manufacturing process low tendency to corrosion.
  • the low Corrosion tendency is mainly due to the low proportion of Attributed to copper and zinc.
  • the process is characterized by the fact that cast Raw material of the alloy at temperatures between 420 ° C and 540 ° C, preferably homogenized between 460 ° C and 500 ° C becomes. During this homogenization, the Alloy components magnesium and silicon fine in the Aluminum matrix also distributes the form Dispersoids, as described, based on zirconium or hafnium, manganese, chromium and / or iron.
  • the raw material Homogenizing for at least 4 hours is particularly preferred a homogenization of 12 h applied.
  • the Semifinished between 500 ° C and 560 ° C, wherein each of the The highest possible temperature to choose is around To avoid recrystallisation nuclei.
  • the semi-finished products will be if necessary, separated into workpieces suitable for forming and either one or several cold formed or possibly several times warm to components or more Reshaped semi-finished products.
  • a machining of the Semi-finished products, z. B. by turning or milling is also appropriate.
  • Hot or cold forming or cutting Editing can be done within the skill of the art take place and optionally conventional heat treatments include.
  • the hot forming of the semifinished product follows at temperatures that are in the range of the usual solution annealing (between 440 ° C and 560 ° C). It is during the reshaping in particular during several forming steps make sure that the Temperature of the workpiece is not below the mentioned Temperature drops, resulting in coarse precipitates in the component structure would result.
  • the forming process replaces the Process step of the solution annealing, which affects considerably the process costs and the duration of the process.
  • the forming temperatures according to the invention are higher than the usual Forming temperatures, resulting in less solidification and thus a lower Rekristallisationskeimön in Microstructure causes.
  • the recrystallization becomes sustainable suppressed.
  • Higher strength values and above all significantly higher elongation at break in highly formed areas are the consequence.
  • the workpiece After forming, the workpiece is preferably in water quenched, which freezes the structure. At the subsequent hot curing between 160 ° C and 240 ° C the desired strength increase takes place.
  • the aluminum component according to the invention produced by a method according to any one of claims 1-8, in one of Alloy information corresponding composition one Tensile strength of at least 400 MPa and a minimum Elongation at break (A5) of 10%.
  • Such components are preferably as tie rods or other chassis parts, Profiles, bolts, screws or wheels used.
  • the Tension struts are quenched in water and at 200 ° C for 4 h artificially aged.
  • the tie rods point both in the area a middle brace as well as in the area of a big eye, due to the high degree of deformation usually one having high degree of recrystallization, a Tensile strength of more than 400 MPa and a breaking elongation (A5) of more than 13%.
