Definitions
- the invention relates to the fields of materials science and process engineering and relates to a method for producing metal-containing castings, as can be used for example for the production of moldings from metallic glasses and an apparatus for implementing this method.
- a metallic glass is a metastable alloy that has no long-range order, unlike normal crystalline materials. Its structure is amorphous and resembles that of a liquid. To obtain the amorphous state on cooling, several conditions must be satisfied. Thus, nucleation and seed growth must be suppressed to freeze the structure of the liquid. To realize this, the metallic melt must be cooled very quickly, for example by contact with the surface of a very good heat-conducting heat sink. The quality of the thermal contact and the thickness and thermal conductivity of the liquid layer determine the cooling rate.
- a well-known and widespread method for casting metals and also massive metallic glasses is the casting into cold molds.
- the melt is forced by different measures in the mold and solidifies there in the form prescribed by the mold.
- the mold is made of good heat conducting material.
- the casting process is very fast. First, the metal is melted in a crucible, and then the melt is forced by gas pressure or centrifugal force into the mold.
- the surface of the mold In order to ensure a good thermal contact between the metallic melt and the mold, advantageously made of copper, the surface of the mold must be very clean. This can be easily realized by mechanical cleaning and pickling.
- the melt should wet the mold well. The wetting depends essentially on the viscosity and interfacial tension of the melt with respect to the copper mold and with respect to the ambient atmosphere. The viscosity depends very much on the temperature. It decreases exponentially with increasing temperature, while the interfacial tensions decrease linearly with increasing temperature. Small values of viscosity and interfacial tension, which are desirable for good wetting and for good filling of the mold, can in principle be set by a high temperature.
- the object of the present invention is to specify a method for producing metal-containing castings and a device therefor, in which in addition high cooling rates and a good mold filling during casting without overheating a metal-containing melt is achieved.
- a metal-containing melt is introduced into an electrically conductive casting mold, wherein the metal-containing melt and the mold are electrically conductively connected to the outputs of the same voltage source during introduction into a casting mold, so that through the boundary layer between the melt and form a preset current flows.
- the metal-containing melt to more than 50 wt .-% of a metal.
- molten amorphous metals are used as metal-containing melt.
- the metal-containing melt is connected via an electrode to a voltage source.
- the introduction of the metal-containing melt into the casting mold is realized by the die-casting method.
- the apparatus according to the invention for producing metal-containing castings there is an electrically conductive connection between a metal-containing melt and a voltage source.
- an electrically conductive mold is present, in which the metal-containing melt is to be introduced, which is also electrically connected to the same voltage source as the metal-containing melt.
- the metal-containing melt is in a device for melting out of metals, even more advantageously in an induction furnace.
- the metal-containing melt is connected via an electrode, advantageously via a tungsten electrode, to a voltage source.
- the metal-containing melt is introduced into the casting mold by means of die casting technology.
- the melting and casting of the metal-containing compounds takes place in a closed system Inert gas atmosphere.
- the likewise advantageously inductively molten metal-containing melt is pressed into the mold, for example by overpressure of the atmosphere, for example argon atmosphere.
- the tension can be changed for each shaping operation or even during a shaping operation.
- a short-circuit current between metal-containing melt and electrically conductive mold is predetermined.
- the main advantage of the solution according to the invention is the specific variability of the wetting behavior between melt and mold without overheating of the melt so that the melt wets the mold better and the contact between melt and mold becomes more homogeneous. Depending on the type of melt, specific property improvements result for different materials.
- Another advantage of the solution according to the invention is that the coercive force of the produced castings is smaller and their magnetization is higher by the application of electrical voltage during the molding process in soft magnetic materials. This is achieved by lower internal stresses during shaping, which is due to the more homogeneous cooling and then leads to improved magnetic and mechanical properties of the product according to the invention. In addition, complex shapes are better formed and the products according to the invention also become mechanically stronger.
- a metallic melt is produced in an induction furnace under argon atmosphere.
- a tungsten electrode which is connected to a voltage source, reaches into the metallic melt.
- the copper mold is also electrically connected to the voltage source. After applying the voltage of 230 V, the outflow opening in the induction furnace is opened. At the same time, an argon overpressure of 200 kPa is applied. As a result, the metallic melt is pressed into the recess in the copper mold and fills it completely due to the lower surface tension. After cooling and opening the copper mold is a complete annular disc with the desired dimensions.
- the alloy Fe B s 1S Cr 4 Mo 4 Ga 4 P-> C 5 B 515 can not be cast amorphously into an annular disk according to the prior art methods. According to the method of Example 1 can now be made of this alloy a complete annular disc, wherein the product is in an amorphous form.
