Definitions

  • the invention relates to a cast component made of an aluminum alloy with good heat resistance.
  • WO-A-0043560 is an aluminum alloy with 2.5 to 7.0 wt.% Mg, 1.0 to 3.0 wt.% Si, 0.3 to 0.49 wt.% Mn, 0.1-0.3% by weight Cr, max. 0.15% by weight of Ti, max. 0.15% by weight of Ti, max. 0.15 wt.% Fe, max. 0.00005 wt.% Ca, max. 0.00005 wt.% Na, max. 0.0002 wt.% P, other impurities individually max. 0.02 wt .-% and aluminum as the remainder for the production of security components in the die-casting, squeeze casting, thixoforming or thixoforging process known.
  • the invention has for its object to provide a suitable for the production of thermally stressed components aluminum alloy with good heat resistance.
  • the alloy should be particularly suitable for gravity die casting, low pressure die casting and sand casting.
  • the components cast from the alloy should have a high strength combined with high ductility.
  • the mechanical properties sought in the component are defined as follows: yield strength Rp0.2> 170 MPa tensile strenght Rm> 230 MPa elongation A5> 6%
  • the corrosion tendency of the alloy should be kept as low as possible, and the alloy must also have a correspondingly good fatigue strength.
  • the castability of the alloy should be better than that of currently used AlSiCu casting alloys, and the alloy should show no tendency to crack.
  • cast component includes in addition to the pure, manufactured only by casting components and those that are cast as a preform and subsequently formed by kneading cold or warm to final dimensions.
  • pure cast components are those which are produced exclusively by sand casting, gravity die casting, low pressure die casting, die casting, thixocasting or squeeze casting.
  • Forming operations performed on a cast preform by kneading include, for example, forging and thixoforging.
  • the following content ranges are preferred: mg 2.5 to 3.5% by weight, in particular 2.7 to 3.3% by weight Si 0.9 to 1.3% by weight Mn 0.15 to 0.3% by weight Cr 0.15 to 0.3% by weight Ti 0.05 to 0.15% by weight Fe Max. 0.15% by weight Cu Max. 0.05% by weight Be 0.002 to 0.005% by weight V 0.01 to 0.1% by weight Zr 0.1 to 0.2% by weight
  • Silicon in conjunction with magnesium leads to a corresponding curing, in particular, the hot curing is of interest.
  • a heat treatment to the condition T6 e.g. a solution annealing at 550 ° C for 12 h with subsequent hot aging at 160-170 ° C for 8 - 10 h.
  • the combination of manganese and chromium leads to a good heat resistance at a continuous temperature of up to 180 ° C.
  • Titanium and zirconium are used for grain refining. A good grain refinement contributes significantly to improve the casting properties.
  • a preferred area of application of the cast components according to the invention are thermally stressed components, in particular pressure vessels, compressor housings and engine components such as cylinder heads in the automotive industry.
  • the components are preferably produced by sand or Kokillengiess vide.
  • Table 1 Chemical composition of the alloys (in% by weight) alloy Si Fe Cu Mn mg Cr Zn Ti Be V Zr AlSi7MgCu1 6.97 00:11 0.94 0005 00:38 0008 00:03 AlMg3Si1MnCr 1.10 00:07 0001 00:20 3.2 00:21 0002 00:12 0003 00:03 0.0005
  • the alloy according to the invention was cast in a sample mold according to Diez into round rods of 16 mm diameter.
  • the mechanical properties yield strength (Rp0.2), tensile strength (Rm) and elongation at break (A5) in state T6 (165 ° C / 6h) after a continuous temperature load of 500 h at different temperatures.
  • the corresponding values for the comparative alloy were taken from the above article by FJ Feikus. The results are shown in Fig. 1 in diagram form.
  • the AlMg3Si1MnCr alloy according to the invention does not reach the peak values of the comparative alloy AlSi7MgCu1 in terms of yield strength and tensile strength, it is "less changeable” in its temperature behavior. This changeability is distracting in operation insofar as slight changes in temperature can cause large changes in the mechanical properties.
  • the yield strength of the inventive alloy remains at about 180 ° C at a nearly same level, gradually falls to 200 ° C and begins to fall off only from about 200 ° C continuously. The continuous waste occurs in comparison with the alloy AlSi7MgCu1 with a lower inclination.
  • the alloy according to the invention is distinguished by an almost constant value up to 180 ° C.
  • High elongation values provide favorable fracture / failure behavior.
  • the breakage of the component is preceded by a visible deformation. Above 180 ° C, the strain increases continuously.
  • Low elongation values cause unfavorable failure behavior, i. the component deforms only slightly or not at all. At load peaks, the component breaks without warning.
