Definitions

  • the invention relates to the use of a Aluminum alloy for thixocasting or thixo forging.
  • This heat treatment is for molding the casting phases and thus necessary to achieve tough fracture behavior.
  • Heat treatment usually means solution annealing at temperatures just below the Solidus temperature with subsequent quenching in Water or other medium at temperatures ⁇ 100 ° C.
  • the material treated in this way now has a low one Yield strength and tensile strength.
  • heat aging is carried out. This can also be done depending on the process, e.g. by a thermal exposure during painting or by the relaxation annealing of an entire component group.
  • JP-A-1149938 is a die casting alloy with 3 to 6% Mg, 0.3 to 2.5% Si, 0 to 2% Mn, 0.03 up to 0.40% Ti and optionally 0.001 to 0.01% Be and Al known as the rest.
  • An example Alloy has the following composition of their main alloy elements: 5% Mg-2.2% Si-0.4% Mn.
  • DE-B-175B441 is an Al cast alloy with 0.6 to 1.2% Mn, 4.5 to 7.5% Mg, 0.8 to 2.5% Si, 0.1 to 0.3% Ti and 0.2 to 1.0% Cu disclosed.
  • GB-A-1384264 describes an Al cast alloy with 3.5 to 7% Mg, 0.8 to 2.5% Si and 0.6 to 1.8% Mn.
  • An alloy given as an example has the following regarding its main alloying elements Composition on: 0.85% Mn, 4.7% Mg as well 1.7% Si.
  • this alloy In the as-cast state, this alloy has a well molded ⁇ -phase.
  • the eutectic mainly consisting of Mg 2 Si and Al 6 Mn phases, is very fine and therefore leads to a highly ductile fracture behavior.
  • the eutectic content of around 30% ensures excellent castability.
  • the manganese content prevents sticking in the mold and ensures good mold release.
  • the magnesium content in combination with manganese gives the casting a high level of strength, so that very little or no distortion can be expected even when demoulded.
  • this alloy is ideal for thixocasting or thixo forging.
  • the ⁇ phase forms immediately when it melts again, so that excellent thixotropic properties. at The usual heating rates become a grain size of ⁇ 100 ⁇ m.
  • the alloy is heat treatable, weldable and shows excellent casting behavior.
  • a preferred use of the inventive Aluminum alloy lies in components with high Requirements for mechanical properties, without the need for heat treatment is.
