Definitions
- the invention relates to a cast lightweight casting material based on aluminum.
- a comparatively higher mechanical and thermal resilience have aluminum-silicon alloys, the matrix of which is reinforced by, for example, 20 vol.% Fibers, such as from Al2O3, carbon, steel and the like, or whiskers, such as from SiC or the like.
- the press casting process is excellently suitable for the production of such fiber composite materials (Bader, MG: Alumina-fiber reinforced aluminum alloy castings for automotive applications, proc. of the int. Ass. For Vehicle Design, Vol. 2, 1984).
- fiber composite materials are comparatively complex in terms of their manufacture.
- Ceramic materials promise significantly improved high-temperature strength and more favorable corrosion behavior.
- the mass production of complex ceramic components e.g. monolithic pistons or turbine blades, however, is still an unsolved problem.
- the possible uses of ceramics in internal combustion engine construction are limited from the outset due to their great sensitivity to notches, mechanical impacts and thermal alternating loads.
- they increase the weight to an undesirable extent, can only be formed with considerable effort and their production is associated with considerable costs.
- Materials based on intermetallic phases combine metallic and ceramic properties, e.g. good thermal conductivity, a high melting temperature and partially satisfactory ductility, so that they appear to be suitable for filling the area between the conventional metallic lightweight materials based on aluminum and the high-temperature-resistant but brittle ceramics. This applies in particular to gas turbines and internal combustion engines in which improved materials enable the operating temperatures and thus the thermal efficiency to be increased.
- intermetallic phases has been used in light-alloy pistons made of aluminum-silicon alloys to the extent that they are eliminated by arc welding in the area of the first piston ring groove when part of the base material is melted and with nickel or copper materials is mixed.
- Hard intermetallic phases and primarily silicon are embedded in a highly supersaturated matrix of aluminum mixed crystal, which results in high wear resistance (US-A-4 562 327).
- an intermetallic phase alloy based on magnesium silicide for the production of moldings of high heat resistance, which contains up to 42% by weight aluminum and / or up to 22% by weight silicon can be added.
- the optimal composition of this alloy is limited by an area in the three-material system aluminum-magnesium-silicon by the eutectic groove, the quasi-binary cut and by 42% by weight aluminum.
- the disadvantage of such a cast light material consists in a gas porosity which cannot always be avoided, which occurs when the residual melt solidifies in the cast body, and on the gases dissolved in the melt, which are released during solidification as a result of the decreasing solubility.
- This task is solved by a light cast material on aluminum basis with the addition of 5 to 25 mass% magnesium silicide.
- This lightweight material primarily contains magnesium silicide and the remainder consists of binary Al-Mg2Si eutectic or ternary Al-Mg2Si-Si eutectic.
- the light material according to the invention can be fine-grained by adding up to 12% by mass, preferably 0.5 to 10% by mass, of silicon, although no primary silicon may occur.
- the silicon can be replaced in whole or in part by up to 15% by mass, preferably 5 to 12% by mass, of magnesium.
- a preferred composition of the lightweight aluminum-based material consists in the three-material system aluminum-magnesium-silicon in a surface on both sides of the quasi-binary cut Al / Mg2Si, which is limited by the liquidus temperature of ⁇ 700 ° C and the primary solidification range of magnesium silicide.
- the curing of the lightweight material can be accelerated considerably.
- the aluminum-based lightweight material according to the invention is produced by means of customary casting processes, either by charging an aluminum melt with magnesium silicide or by adding magnesium and silicon separately to the melt.
- the properties achieved with the invention are compared in the table below with the properties of an aluminum piston alloy of the type G-AlSi12CuMgNi. It shows that the thermal expansion coefficient is lower with 19.8 ⁇ 10 ⁇ 6K ⁇ 61 for a light material with the composition Al80-Mg2Si20.
- the value for the thermal conductivity at 173 W / mK is significantly higher than the value of the thermal conductivity for the conventional piston alloy.
- the density of the lightweight material is reduced to approximately 2.51 g / cm3, while the stiffness of the lightweight material characterized by the modulus of elasticity increases to 83 GPa.
- the remaining mechanical strength values can be influenced by the structure and the heat treatment.
- the composition of the light material based on aluminum which is particularly interesting for a technological use as a piston material, is represented by a hatched area on both sides of the quasi-binary cut Al / Mg2Si, which is characterized by the liquidus temperature of ⁇ 700 ° C and the primary solidification range of magnesium silicide is limited.
