Definitions

  • the invention relates to a process for the preparation of Profiles of light metal material, in particular magnesium material, by extrusion, in which a volume of material through a die, which is the shape of the desired Profiles intended to form the profile is pressed.
  • a major disadvantage of this known method is the achievable limited press speed, which is justified in the process itself, but also in the material volume forming light metal or Light alloy materials.
  • Extrusion or extrusion is the volume of material over the stamp by the shaping Die pressed. This arises between the Material volume and the surrounding recipient a Friction surface, on the one hand to an increase in pressure, on the other hand, but also to a warming of the surface leads. Due to the one-sided on the metal volume in the Recipients applied pressure results as a result, that the flow behavior of the light metal or light alloy material determined by the matrix becomes. This results in a heating of the profile surface, the heating depends on the speed is, with the light metal or light alloy material is pressed through the die. It follows in turn that by means of the known Method the pressing speed is limited insofar as it does to a local melting on the profile surface comes out of the die at the exit. One speaks in this case, the so-called hot cracking.
  • This type can be greatly simplified and much higher production speeds simultaneous improvement of the properties of the produced Profiles should be available, as they are with previous production methods were not achievable, wherein by means of the method in principle in the state oftechnik known extrusion molding or extrusion to be used, i. e. that necessary for the execution of the method apparatus Effort and process management should be largely be carried out by means of per se known techniques can.
  • the production of the fine-grained casting material Material volume according to the invention by a variation of the composition of the material by a conventional light metal or light metal alloy material with proven properties of said grain refiner is supplied. That with the invention aspired and achieved fine-grained microstructure of the light metal or light metal alloy material, preferably Magnesium or magnesium alloy material is so receives such a fine-grained texture that thereby a significant improvement in mechanical properties, especially ductility, measured as Elongation at break in the tensile test is achieved.
  • the deformability of the light metal or Alloy alloy material is also a significant Improvement of the extrusion process achieved, so that the much finer-grained structure of the material volume in the recipient of the extrusion at considerably lower temperatures can be pressed, which also leads to the fact that the sustainable light metal or light metal alloy material profile itself turn is much more fine-grained, resulting in an improvement the material properties of the profile leads and to a much higher pressing speed, since according to the invention the hot cracking of the profile surface avoided becomes.
  • the fine grain of the microstructure of the invention manufacturable profiles also has stabilizing, well-distributed precipitations in the material result, the lead to an increase in the mechanical characteristics.
  • the inventive method can considerably lower temperatures than previous methods be performed.
  • Grain refiners are advantageously the metals Zirconium, strontium and calcium, especially then if magnesium material or magnesium alloy materials form the light metal material.
  • Also suitable as grain refiners are the metals of rare earths, especially if magnesium or magnesium alloy materials the light metal materials form.
  • the method is advantageously carried out in such a way that the temperature of the material volume in the recipient an extrusion device in the execution the extrusion process in the range of 150 to 350 ° C. is located, i. significantly below the temperature ranges, which is needed in conventional extrusion which are in the range of 300 to 450 ° C.
  • the Temperature for the extrusion process depends on both the composition of the light metal or light alloy alloy material from as well as essentially from the pressure exerted on the metal volume in the recipient Print.
  • the speed of the extrusion is up to 250 m min -1 , which corresponds to a nearly doubling of the pressing speeds achievable by means of previous methods.
  • the extrusion by means of a hydrostatic Pressing process has the extraordinary Advantage that by means of hydrostatic extrusion the deformability of the light metal or light alloy material, especially magnesium material, can be significantly increased and the temperatures during the pressing process can be lowered again s, as a result, the friction between the material volume and the surrounding recipient in fact omitted and the applied pressure does not counteract Must overcome frictional forces.
  • the hydrostatic pressing process can thus approximately the entire applied Pressing pressure are used to build up the pressure, to apply for the pressure needed is to push the metal volume through the die.
  • the extrusion molding apparatus 10 shown in FIG. 1, by means of a so-called. "direct" extrusion process is executable includes a recipient 12, in the one Material volume 15, eg. From light metal or Alloy alloy material, in particular magnesium material, is introduced. Concluding the recipient 12, in Figs. 1 and 3 shown on the right is a die 14 is provided to receive the according to desired cross section of the profile 16 is formed is. The die 14 substantially opposite, in the 1 and 3 shown on the left, is a pressure plate 13, comparable to the seal 17 acc. the extrusion device 10 acc. Fig. 3 is provided. On the in the recipient 12 located material volume 15 is on the Pressing disc 13 by means of a punch 11 exerted pressure See Fig. 1. By means not shown here separately Warming agent will be located in the recipient Volume of material 15 is heated and in the course of the pressing process via the die 14 as a strand or profile 16 the extrusion device 10 led out.
  • a recipient 12 in the one Material volume 15, eg. From light metal
  • the extrusion molding device 10 acc. Fig. 3 differs However, from the gem. Fig. 1 in that the Stamp 11 at its free end with a seal 17th is provided, which ensures that the in the recipient 12 arranged material volume 15, which is a pressure fluid 18, the material volume 15 in the recipient 12th surrounds, not exit from the extrusion device 10 can.
  • the die 14 is opposite the recipient 12 provided with a seal 20.
  • the stamp 11 If the stamp 11 is moved into the recipient 12, builds in the recipient 12 via the pressure fluid 18 a on all sides on the material volume 15 impacting pressure on.
  • the pressure builds from all sides equally on the volume of material 15, as a result as a strand or profile 16, the extrusion device 10 leaves.
  • the method for producing profiles 16 from Light metal or light metal alloy materials, especially magnesium materials, by means of extrusion is preferably with an extrusion device 10 acc. Fig. 3, by means of said "hydrostatic" Extrusion is possible, executed.
  • the light metal or light metal alloy material becomes the training of the for the extrusion process usable material volume a grain fine, the For example, zirconium, strontium and calcium are formed can, attached. This turns the microfine structure of the light metal or light metal alloy material refined. As grain refiner also the metals of the rare earths are used.
  • pressing ratio cross-sectional area of the starting material in relation to the cross-sectional area of the profile.
  • Figs. 4 and 5 in which the structure of a continuously cast metal block, ie a material volume 15 from AZ 31 compared to a material modified with zirconium as a fine material designated ME 10, see , Fig. 5, is shown.
  • a comparison of both figures reveals a significant grain refining. It is found for the material AZ 31 particle size 400-600 ⁇ m and for the modified or gefeinten Material ME 10 particle size 100-200 ⁇ m.
  • the Zulegleiters Kunststoff for example, for the application of the hydrostatic extrusion process, s. also Fig. 3, is assembled in Tab. 1.
  • the variation of the base alloys (ME 10, ZE 10, AZ 31 - AZ 61) are given Zulegleiterskonzentrationen.
  • Table 2 shows the composition of alloys, which had been studied by way of example.
