MagnesiumlegierungMagnesium alloy
Die Erfindung betrifft eine Magnesiumlegierung für technische Anwendungszwecke sowie die Verwendung zur Herstellung stranggepreßter Halbzeuge bzw. Bauteile sowie von Blechen.The invention relates to a magnesium alloy for technical applications and to its use for producing extruded semi-finished products or components as well as sheets.
Magnesiumlegierungen sind Leichtbauwerkstoffe, die in der Kraftfahrzeugtechnik, im Motorenbau, in der Luft- und Raumfahrttechnik oder anderen konstruktiven Leichtbau zur Anwendung kommen.Magnesium alloys are lightweight materials that are used in automotive engineering, engine construction, aerospace engineering or other lightweight construction.
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.Reducing weight is particularly important in vehicle construction, as additional elements are being installed due to increasing comfort and safety standards. Lightweight construction is also important for the design of energy-saving vehicles. When processing magnesium materials, the processes of primary forming by die casting and forming by extrusion, forging, rolling, stretching or deep drawing are becoming increasingly important. These processes can be used to produce lightweight components, for which there is a growing demand, particularly in vehicle construction.
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,A magnesium alloy is known from DE 806 055, which has a composition of 0.5 to 10% metals from the rare earth group, the remainder being magnesium, with the proviso that the rare earths consist of at least 50%, preferably at least 75 % neodymium, a maximum of up to 25 % lanthanum and cerium separately or together and praseodymium and small amounts of samarium and traces of the elements from the yttrium group as the remainder, with one or more of the following elements manganese, aluminium,
Calzium, Thorium, Quecksilber, Beryllium, Zink, Cadmium und Zirkon zugesetzt werden.
'5Calcium, thorium, mercury, beryllium, zinc, cadmium and zirconium are added.

Aus der DE 42 08 504 Al ist eine Magnesiumlegierung bekannt, die 2 bis 8 % Seltenerdmetalle enthält, wobei das Seltenerdmetall aus Samarium besteht.From DE 42 08 504 Al a magnesium alloy is known which contains 2 to 8% rare earth metals, whereby the rare earth metal consists of samarium.
Weitere Legierungen, die neben dem Hauptbestandteil Magnesium, Mangan und weitere Elemente aus der Gruppe der sp-Metalle und/oder Aluminium, Kupfer, Eisen, Nickel, Calzium u. a. enthalten, sind beispielsweise aus den DE 199 15 276 Al, DE 196 38 764 Al, DE 679 156, DE 697 04 801 T2, DE 44 46 898 Al bekannt.Other alloys which, in addition to the main component magnesium, contain manganese and other elements from the group of sp metals and/or aluminium, copper, iron, nickel, calcium, etc., are known, for example, from DE 199 15 276 Al, DE 196 38 764 Al, DE 679 156, DE 697 04 801 T2, DE 44 46 898 Al.
Die bekannten Magnesiumlegierungen weisen die unterschiedlichsten Nachteile aus. 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.The known magnesium alloys have a wide range of disadvantages. If calcium is present, hot cracks can occur after casting in a casting process with a high cooling rate, for example in injection molding. In alloys that contain magnesium-aluminium-zinc-manganese or magnesium-aluminium-manganese, the strength decreases at higher temperatures.
Insgesamt verschlechtert sich das Umformverhalten, die Schweißbarkeit oder die Korrosionsbeständigkeit.Overall, the formability, weldability and 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. Viele derThe cold formability of the most common magnesium alloys is limited due to the hexagonal crystal structure and the low ductility. Most magnesium alloys are brittle at room temperature. For certain forming processes for the production of semi-finished products from magnesium alloys, ductile behavior is necessary in addition to high tensile strength. Higher ductility enables improved forming and deformation behavior, and possibly also higher strength and toughness. Many of the

Aufgabe der Erfindung ist es, eine Magnesiumlegierung zu entwickeln, die für die Herstellung von Blechen und Strangpreßprofilen geeignet ist, das heißt, die gute Verformungseigenschaften, eine hohe Korrosionsbeständigkeit sowie eine gute Kaltumformbarkeit besitzt.The object of the invention is to develop a magnesium alloy which is suitable for the production of sheets and extruded profiles, i.e. which has good deformation properties, high corrosion resistance and good cold formability.
Erfindungsgemäß wird dies dadurch erreicht, daß die Legierung einen Gehalt von 96 bis 97,9 % Magnesium, 1,6 bis 2 % Mangan und 0,5 bis 2 % eines Elementes der Gruppe der Seltenerden enthält. Als Element der Gruppe der Seltenerden kommt vorzugsweise Cer zum Einsatz. Die vorgenannten Magnesiumlegierungen ergeben gute Festigkeitseigenschaften über eine größeren Temperaturbereich und einen hohen Kriechwiderstand, bei einer ausreichenden Verformbarkeit. Die erfindungsgemäße Magnesiumlegierung kann Anwendung finden für die Herstellung von Blechen, Halbzeugen oder Strangpreßteilen und - profilen. Daraus können dann spezielle Teile, vorzugsweise für die Anwendung im Fahrzeugbau, wie Sitz-, Fenster- oder Türrahmen, Fahrzeugaußenhäute, Gehäuse, Träger, Halterungen, Stützen und andere Kleinteile hergestellt werden.According to the invention, this is achieved in that the alloy contains 96 to 97.9% magnesium, 1.6 to 2% manganese and 0.5 to 2% of an element from the rare earth group. Cerium is preferably used as the element from the rare earth group. The above-mentioned magnesium alloys provide good strength properties over a wider temperature range and high creep resistance, with sufficient deformability. The magnesium alloy according to the invention can be used for the production of sheet metal, semi-finished products or extruded parts and profiles. Special parts can then be made from this, preferably for use in vehicle construction, such as seat, window or door frames, vehicle outer skins, housings, supports, brackets, supports and other small parts.
Eine besonders vorteilhafte Zusammensetzung der erfindungsgemäßen Magnesiumlegierung ergibt sich, wenn diese aus den Bestandteilen 97,45 % Magnesium, 1,8 % Mangan und 0,75 % Cer besteht.A particularly advantageous composition of the magnesium alloy according to the invention results when it consists of the components 97.45% magnesium, 1.8% manganese and 0.75% cerium.
Die Legierung mit dieser Zusammensetzung zeichnet sich durch eine gute Korrosionsbeständigkeit, ein verbessertes Kaltumformverhalten sowie ein geringeres Warmkriechverhalten aus.
30The alloy with this composition is characterized by good corrosion resistance, improved cold forming behavior and lower hot creep behavior.
