Definitions

the invention relates to aluminum alloy castings subjected to high thermal and mechanical stresses, in particular the cylinder heads and housings of internal combustion engines, and more particularly of turbocharged petrol or diesel engines. There are also, apart from the automobile, parts subject to the same types of constraints, for example in the field of mechanics or aeronautics.
alloys containing 5 to 9% of silicon, 3 to 4% of copper and magnesium are most often secondary alloys, with iron contents of between 0.5 and 1%, and contents of impurities, in particular manganese, zinc, lead, tin or nickel, quite high. These alloys are generally used without heat treatment (state F) or simply stabilized (state T5). Rather, they are intended for the manufacture of cylinder heads for petrol engines with relatively little thermal stress. For the most stressed parts intended for diesel or turbo-diesel engines, primary alloys are used, with an iron content of less than 0.3%, heat treated in the T6 state (returned to the peak of mechanical resistance) or T7 (over-income).
Patent EP 1057900 (VAW Aluminum), filed in 1999, is a development along the same lines and describes the addition to an Al-Si7MgO, 3CuO, 35 alloy of tightly controlled amounts of iron (0.35 - 0.45% ), manganese (0.25 - 0.30% "), nickel (0.45 - 0.55%), zinc (0.10 - 0.15) and titanium (0.11 - 0, 15%).
This alloy has, in states T6 and T7, good creep resistance, high thermal conductivity, satisfactory ductility and good resistance to corrosion.
the object of the present invention is to further improve the mechanical resistance and the creep resistance of molded parts made of AlSiCuMg type alloys in the temperature range 250-300 ° C, without degrading their ductility, and by avoiding the multiplication of elements. which can be a problem with recycling.
the object of the invention is a molded part with high mechanical strength when hot and high creep resistance in alloy composition (% by weight): Si: 5 - 11 and preferably 6.5 - 7.5
the part is preferably treated by dissolving, quenching and returning to the T6 or T7 state.
the invention is based on the observation by the applicant that by adding a small amount of zirconium to a silicon alloy containing less than 1.5% of copper and less than 0.6% of magnesium, it was possible to obtain, on parts molded treated in the T6 or T7 state, good mechanical strength and good creep resistance in the 250-300 ° C range, without loss of ductility. This is achieved without having to use elements like nickel or vanadium which cause recycling problems.
nickel has the disadvantage of reducing the ductility of the part.
the alloy contains from 5 to 11% of silicon, and preferably from 6.5 to 7.5%.
the iron is kept below 0.6%, and preferably below 0.3%, which means that it can be primary or secondary alloys, with a preference for the first fusion when high elongation at break is desired.
Magnesium is a usual addition element for alloys for cylinder heads; at a content of at least 0.15%, and in combination with copper, it makes it possible to improve the mechanical properties at 20 and 250 ° C. Above 0.6%, there is a risk of reducing the ductility at room temperature.
the addition of 0.3 to 1.5%, and preferably 0.4 to 0.7%, of copper makes it possible to improve the mechanical resistance without affecting the resistance to corrosion.
manganese also has a positive effect on the mechanical resistance at 250 ° C, but this effect level off beyond a content of 0.4%.
the titanium content is maintained between 0.05 and 0.25%, which is quite usual for this type of alloy. Titanium contributes to the refining of the primary grain during solidification, but, in the case of the alloys according to the invention, it also contributes, in connection with zirconium, to the formation, during the dissolution of the part.
the heat treatment typically involves dissolving for 3 to 10 hours at a temperature between 500 and 545 ° C., quenching preferably in cold water, waiting between quenching and tempering for 4 to 4 pm, and tempering. from 4 to 10 h at a temperature between 150 and 240 ° C.
the temperature and the duration of the tempering are adjusted so as to obtain either an income at the peak of mechanical resistance (T6) or an over-income (T7).
the parts according to the invention exhibit both a high mechanical strength, good ductility, a hot mechanical strength and a creep resistance greater than those parts of the prior art.
test pieces of each alloy were poured. These test specimens were subjected to a heat treatment comprising a dissolution of 10 h at 540 ° C, preceded for copper alloys B and C by a stage of 4 h at 500 ° C to avoid burning, quenching at cold water, 24 hour maturing at room temperature and 5 hour tempering at 200 ° C.
the alloy C with the addition of zirconium exhibits a markedly improved creep behavior, the deformation under constant load being reduced, as the case may be, from 40 to 75%.
test pieces of the 6 alloys I to N were prepared, the composition of which is indicated in Table 6:
