Description

Die Erfindung betrifft ein Verfahren zur Herstellung einer aluminiumfreien Magnesiumlegierung, die Verwendung zur Herstellung stranggepreßter, stranggegossener oder druckgegossener Halbzeuge bzw. Bauteile sowie von Blechen findet.The invention relates to a method for producing an aluminum-free magnesium alloy, which is used for the production of extruded, continuously cast or die-cast semi-finished products or components and of sheet metal.

Magnesiumlegierungen sind Leichtbauwerkstoffe, die im Vergleich zu den Legierungen anderer Metalle ein sehr niedriges Gewicht haben und finden dort Anwendung, wo ein niedriges Gewicht eine bedeutsame Rolle spielt, insbesondere in der Kraftfahrzeugtechnik, im Motorenbau und in der Luft- und Raumfahrttechnik.Magnesium alloys are lightweight materials that have a very low weight compared to the alloys of other metals and are used where a low weight plays an important role, especially in automotive engineering, engine construction and aerospace engineering.

Bei sehr guten Festigkeitseigenschaften und einem geringen spezifischen Gewicht sind Magnesiumlegierungen als metallische Konstruktionsmaterialien vor allem für den Fahrzeug- und Flugzeugbau von hohem Interesse.With very good strength properties and a low specific weight, magnesium alloys are of great interest as metallic construction materials, especially for vehicle and aircraft construction.

Gerade im Fahrzeugbau wird eine Reduzierung des Gewichts benötigt, da aufgrund steigender Komfort- und Sicherheitsstandards zusätzliche Elemente eingebaut werden. Auch ist der Leichtbau für die Konstruktion von energiesparenden Fahrzeugen von Bedeutung. Bei der Verarbeitung von Magnesiumwerkstoffen kommt den Verfahren - Urformen durch Druckgießen sowie Umformen durch Strangpressen, Schmieden, Walzen, Streck- oder Tiefziehen eine wachsende Bedeutung zu. Mit diesen Verfahren lassen sich Leichtbauteile herstellen, für die insbesondere im Fahrzeugbau wachsender Bedarf besteht.Weight reduction is particularly important in vehicle construction because additional elements are being installed due to increasing comfort and safety standards. Lightweight construction is also important for the construction of energy-saving vehicles. In the processing of magnesium materials, the processes - master forms by die casting as well as forming by extrusion, forging, rolling, stretching or deep drawing are becoming increasingly important. These processes can be used to manufacture lightweight components for which there is growing demand, particularly in vehicle construction.

Zum Stand der Technik gehören Legierungen mit vorteilhaften mechanischen Eigenschaften, insbesondere mit hoher Zugfestigkeit.The prior art includes alloys with advantageous mechanical properties, in particular with high tensile strength.

Bekannt ist aus der DE 806 055 eine Magnesiumlegierung, die durch eine Zusammensetzung von 0,5 bis 10 % Metalle der Gruppe Seltenerden, Rest Magnesium mit der Maßgabe, daß die Seltenerden sich wenigstens zu 50 %, vorzugsweise wenigstens zu 75 % aus Neodym, höchstens bis zu 25 % aus Lanthan und Cer getrennt oder zusammen und aus Praseodym und kleinen Mengen Samarium und Spuren der Elemente der Yttriumgruppe als Rest zusammensetzen, wobei eins oder mehrere der nachfolgenden Elemente Mangan, Aluminium, Calzium, Thorium, Quecksilber, Beryllium, Zink, Kadmium und Zirkon zugesetzt werden.Is known from the DE 806 055 a magnesium alloy consisting of a composition of 0.5 to 10% of metals from the rare earth group, the remainder of magnesium with the proviso that the rare earths are at least 50%, preferably at least 75% neodymium, at most up to 25% lanthanum and Cerium separately or together and composed of praseodymium and small amounts of samarium and traces of the elements of the yttrium group as the remainder, with one or more of the following elements manganese, aluminum, calcium, thorium, mercury, beryllium, zinc, cadmium and zirconium being added.

Aus der DE 42 08 504 A1 ist eine Magnesiumlegierung bekannt, die 2 bis 8 % Seltenerdmetalle enthält, wobei das Seltenerdmetall aus Samarium besteht.From the DE 42 08 504 A1 a magnesium alloy is known which contains 2 to 8% of rare earth metals, the rare earth metal consisting of samarium.

Weitere bekannte Magnesiumlegierungen mit vorteilhaften mechanischen Eigenschaften umfassen Legierungen, welche Zink und Mischungen von Metallen Seltener Erden enthalten, die einen hohen Anteil an Cer aufweisen. Eine solche Legierung enthält etwa 4,5 Gew% Zink und etwa 1,0 Gew% Seltener Erden, welche einen hohen Anteil Cer aufweisen. Diese Legierungen können gute mechanische Eigenschaften erreichen, sind jedoch schlecht gießbar, so daß es schwierig ist, Teile von zufriedenstellender Qualität zu gießen. Bei komplizierten zusammengesetzten teilen kann das Schweißen auf Schwierigkeiten stoßen.Other known magnesium alloys with advantageous mechanical properties include alloys which contain zinc and mixtures of rare earth metals which have a high proportion of cerium. Such an alloy contains about 4.5% by weight of zinc and about 1.0% by weight of rare earths, which have a high proportion of cerium. These alloys can achieve good mechanical properties, but are difficult to cast, making it difficult to cast parts of satisfactory quality. Welding can be difficult with complex composite parts.

Legierungen mit verbesserter Gießbarkeit können durch höhere Zusätze an Zink und Seltenen Erden erhalten werden. Diese neigen aber dazu, spröde zu sein. Dies kann durch eine hydrierende Behandlung vermieden werden, was aber die Herstellung verteuert.Alloys with improved castability can be obtained through higher additions of zinc and rare earths. But these tend to be brittle. This can be avoided by a hydrating treatment, but this makes the production more expensive.

Magnesiumlegierungen mit höherem Gehalt an Komponenten anderer Metalle, wie z.B. Aluminium und Zink, die an sich feinkörnig erstarren, liegen bezüglich ihrer Korrosionseigenschaften wesentlich schlechter als reines Magnesium oder Magnesium-Mangan-Legierungen.Magnesium alloys with a higher content of components of other metals, e.g. Aluminum and zinc, which solidify in fine-grained form, are much worse in terms of corrosion properties than pure magnesium or magnesium-manganese alloys.

Aus der DE 1 433 108 A1 ist eine siliciumhaltige, korrosionsbeständige Magnesiumlegierung mit feinkörnigen Erstarrungsgefüge bekannt. Neben Silicium sind der Magnesiumlegierung Mangan, Zink, Titan und als weitere Legierungskomponenten Aluminium, Kadmium und Silber zugesetzt.From the DE 1 433 108 A1 is a silicon-containing, corrosion-resistant magnesium alloy with fine-grained solidification structure known. In addition to silicon, manganese, zinc, titanium and, as further alloy components, aluminum, cadmium and silver are added to the magnesium alloy.

Weitere Legierungen, die neben dem Hauptbestandteil Magnesium, Mangan und weitere Elemente wie Aluminium, Kupfer, Eisen, Nickel, Calzium u. a. enthalten, sind beispielsweise aus den DE 199 15 276 A1 , DE 196 38 764 A1 , DE 679 156 , DE 697 04 801 T2 , DE 44 46 898 A1 bekannt.Other alloys that contain magnesium, manganese and other elements such as aluminum, copper, iron, nickel, calcium, among others, are from the DE 199 15 276 A1 . DE 196 38 764 A1 . DE 679 156 . DE 697 04 801 T2 . DE 44 46 898 A1 known.

Die bekannten Magnesiumlegierungen weisen die unterschiedlichsten Nachteile auf.The known magnesium alloys have the most diverse disadvantages.

Die US 6 544 357 offenbart eine Magnesium- und Aluminiumlegierung, die 0,1 oder 0,2 Gewichts% bis zu 30 oder 40 Gewichts% La, Ce, Pr, Nd, Sm, Ti, V, Cr, Mu, Zr, Nb, Mo, Hf, Ta, W, Al, Ga, Si, B, Be, Ge, und Sb, nebst anderen Elementen, enthalten. Die Bandbreite der Legierungen, die hier möglicherweise hergestellt werden könnten, ist so breitgefächert und unüberschaubar, dass es für einen Fachmann unmöglich ist, bei der Legierung, die im nachfolgenden beansprucht wird, anzugelangen.The US 6 544 357 discloses a magnesium and aluminum alloy containing 0.1 or 0.2% by weight up to 30 or 40% by weight of La, Ce, Pr, Nd, Sm, Ti, V, Cr, Mu, Zr, Nb, Mo, Hf, Ta, W, Al, Ga, Si, B, Be, Ge, and Sb, among other elements. The range of alloys that could possibly be produced here is so wide and unmanageable that it is impossible for a person skilled in the art to get hold of the alloy which is claimed below.

Bei Anwesenheit von Calzium können Warmrisse nach dem Gießen in einem Gußverfahren mit hoher Abkühlgeschwindigkeit, beispielsweise beim Spritzguß, entstehen. Bei Legierungen, die Magnesium-Aluminium-Zink-Mangan- bzw. Magnesium-Aluminium-Mangan enthalten, vermindert sich die Festigkeit bei höheren Temperaturen.In the presence of calcium, hot cracks can occur after casting in a casting process with a high cooling rate, for example during injection molding. For alloys that contain magnesium-aluminum-zinc-manganese or Containing magnesium aluminum manganese, the strength decreases at higher temperatures.

Insgesamt verschlechtert sich das Umformverhalten, die Schweißbarkeit oder die Korrosionsbeständigkeit.Overall, the forming behavior, weldability or corrosion resistance deteriorate.

Die Kaltverformbarkeit der gebräuchlichsten Magnesiumlegierungen ist aufgrund der hexagonalen Kristallstruktur und der geringen Duktilität begrenzt. Die meisten Magnesiumlegierungen verhalten sich bei Raumtemperatur spröde. Für bestimmte Umformverfahren zur Herstellung von Halbzeugen aus Magnesiumlegierungen ist neben einer hohen Zugfestigkeit ein duktiles Verhalten notwendig. Durch eine höhere Duktilität ist ein verbessertes Umform- und Deformationsverhalten möglich, gegebenenfalls auch eine höhere Festigkeit und Zähigkeit.The cold formability of the most common magnesium alloys is limited due to the hexagonal crystal structure and the low ductility. Most magnesium alloys behave brittle at room temperature. For certain forming processes for the production of semi-finished products from magnesium alloys, in addition to high tensile strength, ductile behavior is necessary. A higher ductility enables an improved forming and deformation behavior, possibly also a higher strength and toughness.

Viele der bekannten Magnesiumlegierungen weisen mit dem Herstellzustand stark variierende Eigenschaften auf. Ein weiterer Nachteil bei der Herstellung von Magnesiumlegierungen liegt darin, daß metallisches Mangan in der Magnesiumschmelze schwer löslich bzw. einen langen Zeitraum benötigt, um in Lösung zu gehen.Many of the known magnesium alloys have widely varying properties with the production state. Another disadvantage in the production of magnesium alloys is that metallic manganese is difficult to dissolve in the magnesium melt or takes a long time to dissolve.

Aufgabe der Erfindung ist es, ein Verfahren zur Herstellung einer aluminiumfreien Magnesiumlegierung anzugeben, die für die Herstellung von Blechen, Schweißdraht, Strangpreß- und/oder Druckgußprofilen bzw. -bauteilen geeignet ist, das heißt, die gute Verformungseigenschaften, eine hohe Korrosionsbeständigkeit, verbesserte Schweißbarkeit, hohe Streckgrenze sowie eine gute Kaltumformbarkeit besitzt.The object of the invention is to provide a method for producing an aluminum-free magnesium alloy which is suitable for the production of sheet metal, welding wire, extruded and / or die-cast profiles or components, that is to say the good deformation properties, high corrosion resistance, improved weldability , high yield strength and good cold formability.

Erfindungsgemäß wird dies gelöst durch Verfahren nach Anspruch 1 oder 2.According to the invention, this is achieved by the method according to claim 1 or 2.

Als Manganverbindungen wird Mangan (II) Chloride eingesetzt.Manganese (II) chlorides are used as manganese compounds.

Als Phosphorverbindung wird Mozanite eingesetzt.Mozanite is used as the phosphorus compound.

Phosphor erhöht in Legierungen die Zugfähigkeit, die Härte und die Korrosionsbeständigkeit.In alloys, phosphorus increases tensile strength, hardness and corrosion resistance.

Die Magnesiumlegierung weist eine Streckgrenze Rp 0,2 von mindestens 120 Mpa auf sowie gute Festigkeitseigenschaften über einen größeren Temperaturbereich und einen hohen Kriechwiderstand, bei einer ausreichenden Verformbarkeit.The magnesium alloy has a yield strength Rp 0.2 of at least 120 Mpa and good strength properties over a larger temperature range and a high creep resistance with sufficient ductility.

Die so hergestellte Magnesiumlegierung kann Anwendung finden, für die Herstellung von Blechen, Halbzeugen oder Strangpreß- und/oder Druckgußteilen und - profilen sowie zur Herstellung von Schweißdrähten. Daraus können dann spezielle Teile, vorzugsweise für die Anwendung im Fahrzeugbau, Zugbau, Schiffbau und Flugzeugbau, wie Sitz-, Fenster- oder Türrahmen, Fahrzeugaußenhäute, Gehäuse, Träger, Halterungen, Stützen und andere Kleinteile hergestellt werden.The magnesium alloy produced in this way can be used for the production of metal sheets, semi-finished products or extruded and / or die-cast parts and profiles, and for the production of welding wires. Special parts, preferably for use in vehicle construction, train construction, shipbuilding and aircraft construction, such as seat, window or door frames, vehicle outer skins, housings, carriers, holders, supports and other small parts can then be produced from this.

Eine Magnesiumlegierung für die Verarbeitung auf Strangpreßanlagen ergibt sich, wenn diese aus aluminiumfreien Magnesium durch Zugeben von 1,0 Gew% Cer, 0,5 Gew% Lanthan, 0,10 Gew% Scandium und 2,0 Gew% Mangan (II) Chlorid hergestellt wird.A magnesium alloy for processing on extrusion plants results if these are made of aluminum-free magnesium Add 1.0 wt% cerium, 0.5 wt% lanthanum, 0.10 wt% scandium and 2.0 wt% manganese (II) chloride.

Eine weitere Magnesiumlegierung ergibt sich, wenn diese aus aluminiumfreien Magnesium durch Zugeben von 1,0 Gew% Cer, 0,5 Gew% Lanthan, und 2,0 Gew% Mangan (II) Chlorid sowie 0,1 Gew% Monazit hergestellt wird.Another magnesium alloy results if it is made from aluminum-free magnesium by adding 1.0% by weight of cerium, 0.5% by weight of lanthanum, and 2.0% by weight of manganese (II) chloride and 0.1% by weight of monazite.

Die Legierungen mit dieser Zusammensetzung zeichnen sich durch eine gute Korrosionsbeständigkeit, ein verbessertes Kaltumformverhalten, ein geringeres Warmkriechverhalten sowie durch eine hohe Streckgrenze aus.The alloys with this composition are characterized by good corrosion resistance, improved cold forming behavior, lower hot creep behavior and a high yield strength.

Diese Magnesiumlegierung kann insbesondere für die Herstellung von Blechen, von Strangpreß- und/oder Druckgußprofilen bzw. -bauteilen sowie für gezogene Schweißdrähte verwendet werden.This magnesium alloy can be used in particular for the production of metal sheets, extruded and / or die-cast profiles or components, and for drawn welding wires.
