Description

Die Erfindung betrifft Legierungen auf Basis von Aluminium, sowie Formteile aus solchen Legierungen.The invention relates to alloys based on aluminum, as well as moldings of such alloys.

Insbesondere im Bereich von Verbrennungsmotoren moderner Kraftfahrzeuge werden zunehmend Anforderungen an die verwendeten Werkstoffe gestellt, wobei geringes Gewicht und hohe thermische sowie mechanische Belastungen gefordert sind. Dies folgt unter anderem aufgrund höherer Verbrennungsdrücke und Verbrennungstemperaturen sowie geringerer Stegbreite zwischen den Zylindern. Bereits eingesetzte, sprühkompaktierte Leichtmetalllegierungen wie etwa AlSi25Cu4Mg werden Insbesondere bei Dieselanwendungen den aktuellen Anforderungen an Zylinderlaufbuchsen nicht mehr gerecht. Auch andere Bauteile, die nicht eingegossen werden, sondern durch mechanische Bearbeitung und/oder durch ein Warmumformverfahren hergestellt werden, genügen den gestiegenen Anforderungen im Motorenbau nicht mehr. Hierbei handelt es sich besonders um hoch beanspruchte Teile wie Kolben oder Pleuel.Especially in the field of internal combustion engines of modern motor vehicles increasingly demands are placed on the materials used, with low weight and high thermal and mechanical loads are required. This is due, among other things, to higher combustion pressures and combustion temperatures, as well as a smaller web width between the cylinders. Already used, spray-compacted light metal alloys such as AlSi25Cu4Mg are no longer able to meet the current requirements for cylinder liners, especially in diesel applications. Other components that are not cast, but are produced by mechanical processing and / or by a hot forming process, no longer meet the increased requirements in engine construction. These are especially highly stressed parts such as pistons or connecting rods.

Besonders bevorzugt sind die erfindungsgemäßen Legierungen durch eine Herstellung gekennzeichnet, bei der eine hohe Abkühlrate vorliegt. Insbesondere bevorzugt kann die Legierung mittels Sprühkompaktierung hergestellt sein, wobei bei der Methode des Sprühkompaktierens im allgemeinen eine besonders hohe Abkühlrate vorliegt. Alternativ können aber auch herkömmliche pulvermetallurgische Verfahren oder auch gießtechnische Verfahren angewendet werden. Die hohe Erstarrungsgeschwindigkeit der Legierung aufgrund der hohen Abkühlrate bevorzugt die Ausscheidung der Aluminide in einer eher globolitischen Form als In einer nadeligen Form, wie dies bei langsamen Erstarrungsgeschwindigkeiten der Fall wäre.The alloys according to the invention are particularly preferably characterized by a preparation in which a high cooling rate is present. Particularly preferably, the alloy can be produced by means of spray compacting, with the method of spray compacting generally having a particularly high cooling rate. Alternatively, however, conventional powder metallurgical processes or casting technology can also be used Procedures are applied. The high solidification rate of the alloy due to the high cooling rate favors the precipitation of the aluminides in a more globular form than in a needle-like form, as would be the case at slow solidification rates.

Dadurch wird ein festigungssteigender Beitrag zu den Legierungen geleistet, ohne dass diese verspröden.As a result, a contribution to increasing the weight of the alloys is made without causing them to become brittle.

Die Aufgabe der Erfindung wird für ein Formteil dadurch gelöst, dass das Formteil zumindest teilweise aus einer Legierung nach einem der Ansprüche 1 oder 2 besteht. Dabei kann es sich bei dem Formteil auch um ein Teil handeln, das nur teilweise aus einer erfindungsgemäßen Legierung besteht, welche beispielsweise in einem weiteren Verarbeitungsschritt durch ein anderes Material umgossen wird. Insbesondere kann es sich bei dem Formteil um einen Zylinderblock eines Kraftfahrzeuges handeln, bei dem Zylinder-Laufbuchsen aus einer erfindungsgemäßen Legierung bestehen und mit einer anderen Legierung umgossen wurden. Insbesondere vorteilhaft kann dabei das Formteil mittels Sprühkompaktieren sowie gegebenenfalls weiterer Verfahrensschritte hergestellt werden.The object of the invention is achieved for a molded part characterized in that the molded part consists at least partially of an alloy according to one of claims 1 or 2. In this case, the molded part may also be a part which only partially consists of an alloy according to the invention which, for example, is encapsulated by another material in a further processing step. In particular, the molded part may be a cylinder block of a motor vehicle in which cylinder liners are made of an alloy according to the invention and encapsulated with another alloy. In particular, the molding can be produced in a particularly advantageous manner by means of spray compacting and optionally further process steps.

Weitere Vorteile und Merkmale einer erfindungsgemäßen Legierung und eines erfindungsgemäßen Formteils ergeben sich aus den nachfolgend geschilderten Ausführungsbeispielen sowie den abhängigen Ansprüchen.Further advantages and features of an alloy according to the invention and a molded part according to the invention will become apparent from the embodiments described below and the dependent claims.

Es zeigt sich, daß insbesondere die Solidustemperatur signifikant gegenüber etwa der Legierung S260 nach oben verschoben werden konnte. Die Legierung L6, welche als einzige kein Kupfer enthält, weist eine besonders hohe Solidustemperatur auf und kann bevorzugt für entsprechende Anforderungen verwendet werden.It can be seen that in particular the solidus temperature could be shifted significantly upwards compared to the alloy S260. The alloy L6, which contains no copper alone, has a particularly high solidus temperature and can preferably be used for corresponding requirements.

Eingießversuche haben zudem gezeigt, daß bei sämtlichen der Legierungen ein im Vergleich zu S260 verbessertes Verzugsverhalten vorlag. Keine der Legierungen zeigte ein Durchschmelzen oder Ausbeulen der Eingießteile. Eine nachteilige Vergröberung der Si-Partikel durch die beim Eingießen stattfindende Temperaturerhöhung und/oder bei einer anschließenden Wärmebehandlung konnte wirkungsvoll verringert werden.Eingießversuche have also shown that in all of the alloys was compared to S260 improved distortion behavior. None of the alloys showed any melting or buckling of the cast parts. A disadvantageous coarsening of the Si particles due to the temperature increase occurring during pouring and / or during a subsequent heat treatment could be effectively reduced.

Eingießversuche zu den bevorzugten beispielhaften Legierungen wurden mit der Zielrichtung vorgenommen, die Legierungen für eingegossene ZylinderLaufbuchsen von Verbrennungsmotoren zu verwenden. Aufgrund der guten thermischen und mechanischen Eigenschaften sind aber auch andere Verwendungen, insbesondere im Bereich von Verbrennungsmotoren, etwa für Pleuelstangen, Kolben oder Zylinderköpfe, vorteilhaft.Casting tests on the preferred exemplary alloys have been made with the aim of using the alloys for cast-in cylinder liners of internal combustion engines. Due to the good thermal and mechanical properties but other uses, especially in the field of internal combustion engines, such as for connecting rods, pistons or cylinder heads, are advantageous.
