Definitions
- the present invention relates to a method for producing metal-matrix composite materials comprising at least a proportion of magnesium or a magnesium alloy and at least one production step in which thixomolding takes place.
- the material magnesium cannot easily be used for certain applications, such as pistons in motor vehicle engines or other aggregate components, especially engines.
- the properties mentioned can be positively influenced by reinforcing the material by means of a second, usually significantly firmer and harder phase. Ceramic or carbon-based short or long fibers or particles are usually used for this. In melt-metallurgical production, these can either be introduced in the form of a porous molded body (so-called prefomn), which is infiltrated with molten metal, or, in the case of particles, can also be introduced into the metallic matrix by stirring. Another possibility for reinforcing a metallic material with fibers or particles is to form the reinforcing component itself or also “in situ”. In addition to the melt metallurgical processes mentioned, metallic composite materials can also be produced by powder metallurgy.
- squeeze casting When using preforms as infiltrable moldings, squeeze casting has established itself as the preferred casting method.
- the molten metal is pressed into the porous fiber or particle body at somewhat lower mold filling speeds, but somewhat higher pressures than in conventional die casting. This creates an almost pore-free composite with closed fiber-matrix connections.
- Ceramic particles When stirring in, ceramic particles are usually supplied as a loose bed of the moving metal melt by trickling or blowing.
- Composite melts of this type can be cast directly in the form of castings or bars.
- the composite material In the in situ process, the composite material is created by a reaction between two or several alloy elements of the metallic matrix or phases of the overall system, usually with the formation of a new, usually intermetallic phase.
- Mg-Mg 2 Si The production and characterization of the Mg-Mg 2 Si system has been described several times. For example, reference is made to the disclosure of DE 41 25 014 A1.
- the emergence of the intermetallic phase in terms of reinforcement can be assigned to the in-situ process. This is usually done by infiltration of Si pre-containing fiber preforms or by excretion of primary magnesium silicide from hypereutectic Mg-Si alloys. While the primary coarse withdrawal after falling below the liquidus line, block-shaped Mg 2 Si precipitates form, the Mg of pure Si 2 Si formed at the reactive conversion in a preform globular one. Mg 2 Si which is ectectically excreted usually shows the characteristic "Chinese script" structure.
- the metallic material is fed as granulate to the thixomolding machine and moved in the direction of the spray nozzle inside a heated cylinder by a screw conveyor.
- the temperature which lies between the liquidus and solidus temperature of the metal, it partially liquefies, while the remaining solid portion is globular.
- the behavior of the thixotropic material is pseudoplastic, which means that the viscosity decreases with increasing shear.
- Thixomolding is particularly suitable for the manufacture of very thin-walled components with a high degree of dimensional accuracy, since the favorable temperature level between the liquidus and solidus means that there are hardly any signs of shrinkage and distortion.
- the infiltration ability of preforms with high fiber and particle contents in classic die casting is not readily available, the method of squeeze casting is preferably used for this, which in turn requires special casting systems.
- the difficulties that can arise with die-cast infiltration are primarily due to the high filling speed of the process and the low pressure that can be exerted on the melt due to the small gate. However, this is required in order to overcome the normally very low tendency towards wetting between the metallic melt and the ceramic molded body.
- the preform must be heated significantly above the melt temperature in order to avoid premature solidification of the melt on the fiber body.
- the method of stirring is primarily reserved for the particulate reinforcements, since the use of fibers can lead to a sharp increase in the viscosity of the melt, which makes homogeneous distribution of the fibers very difficult or even impossible.
- the stirring result depends on the particle size used, the stirrer speed and the temperature. Inadequate choice of parameters can lead to clumping, flushing of the particles into the slag or their sedimentation on the crucible bottom. If the particles and the melt are a reactive system, reaction reactions may occur at the interfaces due to the long contact time between the two phases, which damage the particles.
- An example of this is the magnesium-aluminum oxide system, where magnesium oxide and aluminum are formed during the reaction between the two partners with the decomposition of the particle substance.
- the object of the present invention is to provide a method for producing metal-matrix composites of the type mentioned at the outset, which enables the production of light-metal composites, in particular for use in components subject to high temperatures, which is more variable and less expensive than previously is known method and avoids the disadvantages associated with these.
- the solution to this problem is provided by a method according to the invention for producing metal-matrix composite materials of the type mentioned at the outset with the characterizing features of claim 1.
- the light-metal composite material is produced using the thixomolding method, with a Mg 2 Si Phase with a volume content of at least 2% is stored.
- the particular advantages of the method according to the present invention result from the combination of the thixomolding method with the method for the in-situ production of a metallic composite material.
- Mg-Mg 2 Si composite materials with a volume content of at least 2% Mg 2 Si are to be produced, preferably by adding a granulate of silicon or a silicon alloy and a granulate of magnesium or a magnesium alloy together to the thixomolding process and there under Shear form an at least partially liquid melt that solidifies in the form of a magnesium body.
- Advantages of the process are the wide range of the adjustable volume contents of Mg 2 Si, the possibility to do without fiber or particle preforms and the quantity and size of the Si particles determine the quantity and size of the Mg 2 Si crystals that form to be able to individually change properties such as the thermal expansion coefficient, the modulus of elasticity, the tensile and elastic limit and the wear behavior. In this way, Si contents can be set that cannot be produced by melt metallurgy. The material cast in this way can be fed to subsequent forming operations, such as a forging process.
- a cast body is preferably produced from the metal-matrix composite material, which is then processed further.
- the cast body is subsequently formed in at least one process step.
- Such a forming process can include, for example, at least one forging process.
- the present invention furthermore relates to metal-matrix composite materials which have been produced by the process according to the invention.
- the present invention furthermore relates to the use of metal-matrix composite materials produced by a method having the features of one of claims 1 to 11 for the production of components for motor vehicles.
- These are preferably motor vehicle components made of light metal composites which are exposed to high temperature loads, for example engine parts such as pistons or the like.
- Metal-matrix composite materials that were produced by the method according to the invention can be used, for example, for the production of pistons or other engine parts for engines operated with diesel fuel or gasoline fuel.
- the metal-matrix composite materials are furthermore suitable, for example, for the production of liners for shafts, cylinders and other rotationally symmetrical parts, in particular in engines. They are also suitable for the production of other motor vehicle parts subject to wear, such as brake discs.
- the volume content of the Mg 2 Si phase in the metal matrix is preferably in the range between about 5 and about 40 percent by volume receive an addition of Si.
- the reaction 2 Mg + Si - Mg 2 Si is essential.
- an addition of at least about 2 percent by weight of Si and preferably a maximum of about 15 percent by weight of Si is suitable.
- the resulting volume percentages of Mg 2 Si are listed in Table 1 below, which represent exemplary proportions of Mg 2 Si phase in the metal-matrix composite.
- Mg 2 Si is a comparatively high-melting phase with a melting point close to 1,100 ° C. This phase is therefore suitable as a reinforcement to improve the high-temperature properties of the matrix material. This applies to creep behavior as well as parameters such as thermal conductivity and thermal expansion coefficient. In addition to other physical and mechanical properties, these values can be set specifically for an application. The exact numerical values depend, among other things, on the base alloy, the volume fraction of Mg 2 Si, further precipitations in the matrix alloy, and also on the operating temperature or the operating temperature range. These data are to be determined experimentally for the respective application.
- Mg 2 Si precipitates Another influencing factor is the form of the Mg 2 Si precipitates. They are usually found as so-called "Chinese script" excretions, ie as needle-shaped excretions, which are very similar in shape to Chinese characters. However, the addition of alloying elements such as Ca results in primary polygonal excretions that look like one Both types of excretion also have an effect on mechanical and physical properties.
- the parameters selected in the further processing have a significant effect on the property profile. If reshaping takes place, for example, by extrusion, the alignment of planes of the Mg crystallites parallel to the extrusion direction leads to anisotropy.
- the magnitude of the anisotropy depends on various factors, in particular on the forming ratio, the temperature in the tool, the preheating, heat control after pressing and thus the dynamic and static recrystallization.
- the alloy composition including the influence of impurities is also an influencing factor.
- the temperature control in the production of metal matrix composites by the method according to the invention is directly related to the selected alloy, the shot weight and the tool, in particular its component geometry, sprue etc., the geometry of the screw and cylinder during thixomolding, the feed rate and also the shooting speed. These parameters must be determined empirically for each component and are also dependent on the type of machine and its data profile. Similarly, the properties also depend on the solid phase component. This influences the mechanical properties of the matrix alloy alone as well as that of the composite material, i.e. H. the combination of matrix and reinforcement.
- the reaction 2 Mg + Si ⁇ Mg 2 Si means that although the alloys build up a high proportion of the liquid phase more quickly, an increase in the solid phase due to the formation of Mg 2 Si occurs at the same time.
- the reaction not only takes place in the cylinder screw area of the Thixomolding machine, but can also take place in the workpiece after casting. This behavior can be expected especially in areas with material accumulations. Under certain circumstances, a reprint can therefore be applied more successfully, since the exothermic reaction means that some of the matrix alloy is still in the molten phase. Conclusions can be drawn from this by examining metallographic sections.
- the melting interval plays a major role.
- the AZ91 alloy is listed, whose melting range is in the range from 440 to 600 ° C. It is known from the literature that for this alloy a high proportion of liquid phase in the range of 95% leads to an improvement in the mechanical properties in the component. With such a liquid phase component, one can speak of an undercooled melt. After injection into the tool, the result of the method according to the invention is therefore a high nucleation rate with a very high number of germs. This leads to the development of a very fine structure, which has very good mechanical properties due to the Hall-Petsch relationship. Due to the subcooling of the melt, the overall shrinkage is very low. The lower the proportion of liquid phase, the lower it is.
- the grain size of the granules is usually not a determining size. Depending on the machine and the selected component, a different screw geometry can then be selected. The grain size and the grain shape must be matched to the screw geometry. This is completely independent of the alloy or the composite material. The grain size ratio Mg-Si must then be coordinated. However, this is usually only useful for a previously defined screw geometry.
- Granules can be added, for example, by means of a simple conveyor device at the same time or shortly after the granules are fed (both materials are still solid), which can also be attached to the machine.
- a machine of conventional design can be used, such as is available on the market from the companies Thixomat or Japan Steel Works.
