Definitions

  • the invention concerns a casting of an aluminium alloy with good heat resistance.
  • WO-A-0043560 discloses an aluminium alloy with 2.5-7.0 w. % Mg, 1.0-3.0 w. % Si, 0.3-0.49 w. % Mn, 0.1-0.3 w. % Cr, max. 0.15 w. % Ti, max. 0.15 w. % Fe, max. 0.00005 w. % Ca, max. 0.00005 w. % Na, max. 0.0002 w. % P, other contaminants individually max. 0.02 w. % and aluminium as the remainder, for the production of safety components in diecasting, squeeze casting, thixoforming and thixoforging processes.
  • the invention is based on the object of preparing an aluminium alloy with good heat resistance suitable for the production of thermally stressed components.
  • the alloy is particularly suitable for gravity diecasting, low pressure chilled casting and sand casting.
  • Components cast from the alloy should have a high strength in connection with high ductility.
  • the desired mechanical properties of the component are defined as follows: Yield strength Rp0.2 > 170 MPa Tensile strength Rm > 230 MPa Elongation at fracture A5 > 6%
  • the corrosion tendency of the alloys should be kept as low as possible and the alloy must have a correspondingly good fatigue strength.
  • the castability of the alloy should be better than that of the AlSiCu casting alloys which are currently used, and the alloy should have no tendency to heat cracks.
  • casting includes, as well as the pure components produced solely by casting, those cast as a premould and subsequently formed to the final dimensions by hot or cold shaping.
  • pure castings are those which are produced exclusively by sand casting, gravity diecasting, low pressure chilled casting, diecasting, thixocasting or squeeze casting.
  • Forming operations performed on a cast premould by shaping are for example forging and thixoforging.
  • the object according to the invention is achieved by an aluminium alloy with
  • the following content ranges are preferred for the individual alloy elements: Mg 2.5 to 3.5 w. %, in particular 2.7 to 3.3 w. % Si 0.9 to 1.3 w. % Mn 0.15 to 0.3 w. % Cr 0.15 to 0.3 w. % Ti 0.05 to 0.15 w. % Fe max. 0.15 w. % Cu max. 0.05 w. % Be 0.002 to 0.005 w. % V 0.01 to 0.1 w. % Zr 0.1 to 0.2 w. %
  • Silicon in conjunction with magnesium leads to a corresponding hardening where in particular thermal hardening is of interest.
  • Preferred is heat treatment to a state T6 e.g. solution annealing at 550° C. for 12 hours with subsequent artificial ageing at 160-170° C. for 8 to 10 hours.
  • the combination of manganese and chromium leads to good heat resistance at a sustained temperature of up to 180° C.
  • Titanium and zirconium are used for grain refining. Good grain refining makes a substantial contribution to an improvement in casting properties.
  • a preferred area of application of the castings according to the invention is thermally stressed components, in particular pressure vessels, compressor housings and engine components such as cylinder heads in automobile construction.
  • the components are preferably produced in the sand casting or chilled casting process.
  • FIGS. 1-3 tensile strength, yield strength and elongation at fracture as a function of temperature after 500 hours sustained temperature load for an alloy according to the invention and a comparison alloy according to the prior art.
  • the alloy according to the invention was cast in a trial rod mould according to Diez for round rods 16 mm diameter.
  • the mechanical properties of yield strength (Rp0.2), tensile strength (Rm) and elongation at fracture (A5) were determined on the trial rods in state T6 (165° C./6 hours) after a sustained temperature load of 500 hours at various temperatures.
  • the corresponding values for the comparison alloy were taken from the above article by F. J. Feikus. The results are shown in FIG. 1 in diagram form.
  • the alloy AlMg3Si1MnCr according to the invention admittedly does not reach the peak values of the comparison alloy AlSi7MgCu1 with regard to yield strength and tensile strength, but in its temperature behaviour is “less changeable”. This changeability has a disruptive effect in operation insofar as slight changes in temperature can cause great changes in mechanical properties.
  • the yield strength of the alloy according to the invention remains at around the same level up to around 180° C., gradually falls away up to 200° C., and only above around 200° C. begins to decrease continuously. The continuous decrease takes place with a lesser gradient than the alloy AlSi7MgCu1.
  • the alloy according to the invention is characterised by an almost constant value up to 180° C.
  • High elongation values give a favourable fracture/failure behaviour. A visible deformation precedes the break of the component. Above 180° C. the elongation rises continuously.
  • the comparison alloy AlSi7MgCu1 the clear hardening effect can be seen.
  • Low elongation values cause an unfavourable failure behaviour i.e. the component only deforms slightly or not at all. Under load peaks the component breaks without warning.
