Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zur Herstellung einer Aluminium-Legierung, insbesondere für den Druckguss.The invention relates to a method for producing an aluminum alloy, in particular for die casting.
Zur Herstellung von Druckgussbauteilen werden meist AlSiMg-Legierungen verwendet, vor allem die Legierung AlSi9MgMnSr, die unter unterschiedlichen Handelsnamen wie "Silafont 36", "Aural 2" und dergleichen vertrieben werden. Bei diesen Legierungen ist das Eisen weitgehend durch Mangan ersetzt. Bei noch ausreichender Verringerung der Klebeneigung sollen aufgrund des reduzierten Eisengehalts und der Strontiumzugabe Verbesserungen in der Dehnung erzielt werden. Damit zeichnen sich diese Druckgusslegierungen neben einer ausgezeichneten Giessbarkeit durch eine sehr gute Dehnung im Gusszustand, höchste Dehnung nach Wärmebehandlung und darüber hinaus durch eine sehr gute Korrosionsbeständigkeit aus.AlSiMg alloys, especially the AlSi9MgMnSr alloy, which are sold under different trade names such as "Silafont 36", "Aural 2" and the like, are mostly used for the production of die-cast components. In these alloys, the iron is largely replaced by manganese. With sufficient reduction in tack, improvements in elongation are expected due to the reduced iron content and strontium addition. As a result, these die cast alloys are characterized not only by excellent castability but also by very good elongation in the cast state, maximum elongation after heat treatment and, moreover, by very good corrosion resistance.
In der Automobilindustrie ist es von Bedeutung, eine bestimmte Legierung nicht nur von einem sondern von verschiedenen Herstellern beziehen zu können, damit z. B. bei Ausfall eines Herstellers kein Lieferengpass entsteht. Ferner sollen die Legierungen einzelner Hersteller miteinander vermischt werden können, ohne dass schmelzmetallurgische Probleme entstehen. Es hat sich jedoch gezeigt, dass, wenn die AlSi9MgMnSr-Legierungen verschiedener Hersteller vermischt werden, mitunter Legierungen entstehen können, die sowohl in gefügetechnischer Hinsicht wie in ihren dynamischen und statischen Eigenschaften unzureichend sind, und dies trotz gleicher chemischer Zusammensetzung.In the automotive industry, it is important to be able to obtain a particular alloy not only from one but from different manufacturers, so z. B. in case of failure of a manufacturer no supply bottleneck arises. Furthermore, the alloys of individual manufacturers should be able to be mixed together without melting-metallurgical problems. It has been found, however, that when the AlSi9MgMnSr alloys from different manufacturers are mixed, it is sometimes possible to produce alloys which are unsatisfactory both in terms of joining technology and in terms of their dynamic and static properties, and despite their chemical composition.
Aufgabe der Erfindung ist es daher, ein einfaches Verfahren zur Herstellung einer AlSi9MgMnSr-Legierung bereitzustellen, die zumindest gleich gute Eigenschaften wie die handelsüblichen AlSi9MgMnSr-Legierungen aufweist.The object of the invention is therefore to provide a simple process for producing an AlSi9MgMnSr alloy which has at least as good properties as the commercially available AlSi9MgMnSr alloys.

Der Anspruch 4 hat die Verwendung der erfindungsgemäßen hergestellten Legierung zur Herstellung von Druckgussbauteilen zum Gegenstand.This is inventively achieved by the method characterized in claim 1. In claims 2 and 3 preferred embodiments of the method according to the invention are given. The claim 4 has the use of the alloy according to the invention for the production of die-cast components for the subject.
