Description

Die Erfindung betrifft die Verwendung einer Aluminiumlegierung zum Druckgiessen.The invention relates to the use of an aluminum alloy for die casting.

Die Druckgusstechnik hat sich heute soweit entwickelt, dass es möglich ist, Gussstücke mit hohen Qualitätsansprüchen herzustellen. Die Qualität eines Druckgussstückes hängt aber nicht nur von der Maschineneinstellung und dem gewählten Verfahren ab, sondern in hohem Masse auch von der chemischen Zusammensetzung und der Gefügestruktur der verwendeten Gusslegierung. Diese beiden letztgenannten Parameter beeinflussen bekanntermassen die Giessbarkeit, das Speisungsverhalten (G. Schindelbauer, J. Czikel "Formfüllungsvermögen und Volumendefizit gebräuchlicher Aluminiumdruckgusslegierungen" Giessereiforschung 42, 1990, S. 88/89), die mechanischen Eigenschaften und -- im Druckguss ganz besonders wichtig -- die Lebensdauer der Giesswerkzeuge (L.A. Norström, B. Klarenfjord, M. Svenson "General Aspects on Wash-out Mechanism in Aluminium Diecasting Dies", 17. International NADCA Diecastingcongress 1993, Cleveland OH).Die casting technology has developed so far today that it is possible to make castings with high quality standards to manufacture. The quality of a die-cast piece depends but not only on the machine setting and the selected one Process, but also to a large extent from the chemical Composition and structure of the used Cast alloy. These two latter parameters are known to influence the pourability, the feeding behavior (G. Schindelbauer, J. Czikel "Mold filling capacity and volume deficit of common aluminum die casting alloys " Foundry Research 42, 1990, pp. 88/89), the mechanical properties and - especially in die casting important - the service life of the casting tools (L.A. Norström, B. Klarenfjord, M. Svenson "General Aspects on Wash-out Mechanism in Aluminum Diecasting Dies ", 17th International NADCA Diecasting Congress 1993, Cleveland OH).

In der Vergangenheit wurde der Entwicklung von speziell für den Druckguss anspruchsvoller Gussstücke geeigneten Legierungen wenig Aufmerksamkeit geschenkt. Die meisten Anstrengungen wurden auf die Weiterentwicklung der Verfahrenstechnik des Druckgussprozesses verwendet. Gerade von Konstrukteuren der Automobilindustrie wird aber immer mehr gefordert, schweissbare Bauteile mit hoher Duktilität im Druckguss zu realisieren, da bei hohen Stückzahlen der Druckguss die kostengünstigste Produktionsmethode darstellt.In the past, the development of specially for die casting of demanding alloys suitable for castings paid little attention. Most effort were on the advancement of process engineering of the die casting process. Especially by designers the automotive industry is being challenged more and more, weldable components with high ductility in die casting to be realized, since the die casting for large quantities represents the cheapest production method.

Damit die geforderten mechanischen Eigenschaften, insbesondere eine hohe Bruchdehnung, erreicht werden können, müssen die Gussteile einer Wärmebehandlung unterzogen werden. Diese Wärmebehandlung ist zur Einformung der Gussphasen und damit zur Erzielung eines zähen Bruchverhaltens notwendig. Eine Wärmebehandlung bedeutet in der Regel eine Lösungsglühung bei Temperaturen knapp unterhalb der Solidustemperatur mit nachfolgendem Abschrecken in Wasser oder einem anderen Medium auf Temperaturen <100°C. Der so behandelte Werkstoff weist nun eine geringe Dehngrenze und Zugfestigkeit auf. Um diese Eigenschaften auf den gewünschten Wert zu heben, wird anschliessend eine Warmauslagerung durchgeführt. Diese kann auch prozessbedingt erfolgen, z.B. durch eine thermische Beaufschlagung beim Lackieren oder durch das Entspannungsglühen einer ganzen Bauteilgruppe.So that the required mechanical properties, in particular a high elongation at break, must be achieved the castings are subjected to a heat treatment. This Heat treatment is for molding the casting phases and necessary to achieve tough fracture behavior. Heat treatment usually means solution annealing at temperatures just below the solidus temperature with subsequent quenching in water or another Medium at temperatures <100 ° C. The material treated in this way now has a low yield strength and tensile strength. Around to raise these properties to the desired value then heat aging is carried out. This can also take place due to the process, e.g. through a thermal Exposure when painting or by relaxation annealing an entire component group.

Da Druckgussstücke endabmessungsnah gegossen werden, haben sie meist eine komplizierte Geometrie mit dünnen Wandstärken. Während des Lösungsglühens und besonders beim Abschreckprozess muss mit Verzug gerechnet werden, der eine Nacharbeit z.B. durch Richten der Gussstücke oder im schlimmsten Fall Ausschuss nach sich ziehen kann. Die Lösungsglühung verursacht zudem zusätzliche Kosten und die Wirtschaftlichkeit dieser Produktionsmethode könnte wesentlich erhöht werden, wenn Legierungen zur Verfügung stehen würden, die die geforderten Eigenschaften ohne eine Wärmebehandlung erfüllen.Since die castings are cast close to their final dimensions, they usually have a complicated geometry with thin walls. During solution annealing and especially during the quenching process delay must be expected, the one Rework e.g. by straightening the castings or in worst case rejects. Solution annealing causes additional costs and Economics of this production method could be essential be increased if alloys are available would have the required properties without a heat treatment fulfill.

Eine beispielhaft angeführte Legierung weist folgende Zusammensetzung bezüglich ihrer Hauptlegierungselemente auf: 5% Mg-2,2% Si- 0,4% Mn.JP-A-1149938 is a die casting alloy with 3 to 6% Mg, 0.3 to 2.5% Si, 0 to 2% Mn, 0.03 to 0.40% Ti and optionally 0.001 to 0.01% Be and Al are known as the remainder. An example Alloy mentioned has the following composition with respect to their main alloying elements: 5% Mg-2.2% Si-0.4% Mn.

In DE-B-1758441 ist eine Al-Gusslegierung mit 0,6 bis 1,2% Mn, 4,5 bis 7,5% Mg, 0,8 bis 2,5% Si, 0,1 bis 0,3% Ti sowie 0,2 bis 1,0% Cu offenbart. DE-B-1758441 describes an Al cast alloy with 0.6 to 1.2% Mn, 4.5 to 7.5% Mg, 0.8 to 2.5% Si, 0.1 to 0.3% Ti and 0.2 to 1.0% Cu disclosed.

GB-A-1384264 beschreibt eine Al-Gusslegierung mit 3,5 bis 7% Mg, 0,8 bis 2,5% Si sowie 0,6 bis 1,8% Mn. Eine beispielhaft angegebene Legierung weist bezüglich ihrer Hauptlegierungselemente die folgende Zusammensetzung auf: 0,85% Mn, 4,7% Mg sowie 1,7% Si.GB-A-1384264 describes an aluminum casting alloy with 3.5 to 7% Mg, 0.8 to 2.5% Si and 0.6 to 1.8% Mn. An example Alloy specified with regard to their main alloy elements the following composition: 0.85% Mn, 4.7% Mg and 1.7% Si.

Angesichts dieser Gegebenheiten hat sich der Erfinder die Aufgabe gestellt, eine Aluminium-Gusslegierung zu entwickeln, die folgende Eigenschaften aufweist:

  • gute mechanische Eigenschaften im Gusszustand, insbesondere eine hohe Bruchdehnung
  • gute Vergiessbarkeit
  • keine Klebeneigung, gute Entformbarkeit
  • hohe Gestaltsfestigkeit
  • gute Schweissbarkeit
In view of these circumstances, the inventor set himself the task of developing an aluminum casting alloy that has the following properties:
  • good mechanical properties in the as-cast state, especially a high elongation at break
  • good pourability
  • no tendency to stick, good release properties
  • high design stability
  • good weldability

Zur erfindungsgemässen Lösung der Aufgabe führt eine Aluminiumlegierung bestehend aus

  • 4,6 bis 5,8 Gew.% Magnesium
  • 1,8 bis 2,5 Gew.% Silizium
  • 0,5 bis 0,9 Gew.% Mangan
  • max. 0,2 Gew.%, insbesondere 0,1 bis 0,2 Gew.-% Titan
  • max. 0,15 Gew.% Eisen
    • sowie Aluminium als Rest mit weiteren Verunreinigungen einzeln max. 0,02 Gew.%, insgesamt max. 0,2 Gew.%. Der zur Herstellung der Legierung verwendete Reinheitsgrad des Aluminiums entspricht einem Hütten-Aluminium der Qualität Al99.8H.An aluminum alloy consisting of leads to the achievement of the object according to the invention
  • 4.6 to 5.8% by weight of magnesium
  • 1.8 to 2.5% by weight silicon
  • 0.5 to 0.9% by weight of manganese
  • Max. 0.2% by weight, in particular 0.1 to 0.2% by weight of titanium
  • Max. 0.15% by weight iron
    • and aluminum as the rest with further impurities individually max. 0.02% by weight, total max. 0.2% by weight. The degree of purity of the aluminum used to produce the alloy corresponds to that of aluminum of Al99.8H quality.

    Diese Legierung weist im Gusszustand eine gut eingeformte α-Phase auf. Das Eutektikum, überwiegend bestehend aus Mg2Si- und Al6Mn-Phasen, ist sehr fein ausgebildet und führt daher zu einem hochduktilen Bruchverhalten. Der eutektische Anteil von etwa 30% gewährleistet eine ausgezeichnete Giessbarkeit. Durch den Anteil an Mangan wird das Kleben in der Form vermieden und eine gute Entformbarkeit gewährleistet. Der Magnesiumgehalt in Verbindung mit Mangan gibt dem Gussstück eine hohe Gestaltsfestigkeit, so dass auch beim Entformen mit sehr geringem bis gar keinem Verzug zu rechnen ist.This alloy has a well molded α phase in the as-cast state. The eutectic, mainly consisting of Mg 2 Si and Al 6 Mn phases, is very fine and therefore leads to a highly ductile fracture behavior. The eutectic content of around 30% ensures excellent castability. The manganese content prevents sticking in the mold and ensures good mold release. The magnesium content in combination with manganese gives the casting a high level of design stability, so that very little or no distortion can be expected even when demoulded.

    Obwohl die erfindungsgemässe Aluminiumlegierung zur Verarbeitung im Druckguss vorgesehen ist, kann sie selbstverständlich auch mit anderen Verfahren vergossen werden, z.B.

  • Sandguss
  • Schwerkraftkokillenguss
  • Niederdruckguss
  • Giessschmieden
  • Thixocasting/Thixoschmieden
    • Although the aluminum alloy according to the invention is intended for processing in die casting, it can of course also be cast using other methods, for example
  • Sand casting
  • Gravity die casting
  • Low pressure casting
  • Foundry forging
  • Thixocasting / thixo forging

    • Die grössten Vorteile ergeben sich jedoch bei Giessverfahren, die mit hohen Abkühlungsgeschwindigkeiten ablaufen, wie beispielsweise beim Druckgiessverfahren.However, the biggest advantages come from casting processes, that run at high cooling rates, such as the die casting process.

    Weitere Vorteile, Merkmale und Einzelheiten der erfindungsgemässen Aluminium-Gusslegierung sowie deren hervorragende Eigenschaften ergeben sich aus der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels.Further advantages, features and details of the inventive Cast aluminum alloy and its excellent Properties result from the following description of a preferred embodiment.
