Definitions

  • the reduction of the Cu content to a maximum of 0.05% by weight, preferably a maximum of 0.01% by weight, has a similar effect, while at the same time the tendency to filiform corrosion or intergranular corrosion due to the reduction in the Cu content generally declining.
  • the homogenization at a temperature of 500 ° C. to 600 ° C. for at least 0.5 h, preferably at least 2 h ensures that a homogeneous structure is achieved the further processing of the billet is provided.
  • the hot rolling temperatures enable good recrystallization during hot rolling so that the structure is as fine-grained as possible after hot rolling. This fine-grain structure is only stretched by cold rolling and recrystallized again in the final soft annealing.
  • the cold rolling produces a particularly high number of dislocations in the structure, which in the final soft annealing produces a very fine-grain, fully recrystallized structure.
  • the degree of rolling of the final thickness before the final soft annealing must be at least 50%, preferably at least 70% of the desired final thickness.
  • the homogenization takes place in two stages, whereby the rolling billet is first heated to 550 ° C to 600 ° C for at least 0.5 h and then the rolling billet at 450 ° C to 550 ° for at least 0.5 h, preferably at least 2 h. The billet is then hot rolled.
  • An aluminum alloy strip or sheet can be produced from an aluminum alloy according to the invention, the strip having a thickness of 0.2 mm to 5 mm and, in the soft-annealed state, a yield point R p0.2 of at least 45 MPa and a uniform elongation A g of at least 23% and an elongation at break A 80mm of at least 35%.
  • the prerequisites are given that the aluminum alloy strip or sheet can be used for components in motor vehicles which, in addition to very good forming properties, also have very good Have resistance to intergranular corrosion or filiform corrosion. This also applies in particular to painted or coated components.
  • the stated object is achieved by a structural part of a motor vehicle, in particular an inner door part of a motor vehicle, comprising at least one formed sheet metal from a Aluminum alloy according to the invention solved.
  • the aluminum alloy according to the invention not only provides the required forming properties in the soft-annealed state, but also ensures the necessary corrosion resistance and strength of the structural parts at the same time.
  • the structural part according to the invention is produced from a strip which has been produced using the method described. It has been shown that the forming properties as well as the strength properties of the structural part can be achieved in a process-reliable manner with the method, so that an economical production of the structural parts that meet the stated requirements is possible.
  • the degree of rolling must be at least 50%, preferably at least 70%, in order to produce a sufficiently fine-grain structure during the final soft annealing.
  • the final soft annealing in which the strip recrystallizes again, takes place in the chamber furnace at 300 ° C. to 400 ° C., preferably at 330 ° C. to 370 ° C. in step 10.
  • inventive alloy components of Mg, Si, Fe and Mn it is used a continuous furnace for the production of the aluminum alloy strip is not possible, since other structures would be provided due to the different heating and cooling speeds.
