Description

Aluminiumlegierung aluminum alloy
Die Erfindung betrifft eine Aluminiumlegierung,"' insbesondere eine Aluminiumlegierung, welche neben Aluminium Magnesium und Silizium als Hauptlegierungsbestandteile enthält und für die Verwendung im Druckguß und verwandten Verfahren vorgesehen ist.The invention relates to an aluminum alloy, '' in particular an aluminum alloy, which in addition to aluminum contains magnesium and silicon as main alloying components and is intended for use in die casting and related methods.
Aluminium-Druckgußteile haben insbesondere im Automobilbau besondere Bedeutung erlangt . Den steigenden mechanischen Anfor- derungen an Aluminium-Druckgußteile im Automobilbau, ausgelöst vor allem durch die gewichtsbedingte Substitution von Stahlkomponenten durch solche aus ' Aluminiumlegierungen, begegnet man durch den Einsatz spezieller AlSiMg- bzw. AlMgSi-Druckgußlegie- rungen und einer dem Gießprozeß nachfolgenden Wärmebehandlung. Aus AT 407 533 ist beispielsweise eine Aluminiumlegierung mit >3,0 bis 7,0 Gew. -% Magnesium, 1,0 bis 3,0 Gew.-% Silizium, 0,3 bis 0,49 Gew.-% Mangan, 0,1 bis 0,3 Gew.-% Chrom, 0 bis 0,15 Gew.-% Titan, max. 0,15 Gew.-% Eisen und jeweils max. 0,00005 Gew.-% Kalzium und Natrium und max. 0,0002 Gew.-% Phos- phor bekannt .Aluminum die casting parts have become particularly important in the automotive industry. The increasing mechanical demands on aluminum die-cast parts in the automotive industry, mainly caused by the weight-related substitution of steel components with ones from 'aluminum alloys, is combated by the use of special AlSiMg or AlMgSi Druckgußlegie- conclusions and subsequent to the casting process heat treatment. From AT 407 533, for example, an aluminum alloy with> 3.0 to 7.0% by weight of magnesium, 1.0 to 3.0% by weight of silicon, 0.3 to 0.49% by weight of manganese, 0 , 1 to 0.3% by weight of chromium, 0 to 0.15% by weight of titanium, max. 0.15 wt .-% iron and each max. 0.00005% by weight of calcium and sodium and max. 0.0002 wt .-% Phosphor known.
In der EP-B-O 792 380 ist eine Legierung beschrieben, welche 3,0 bis 6,0, bevorzugt 4,6 bis 5,8 Gew.-% Magnesium, 1,4 bis 3,5, bevorzugt 2,0 bis 2,8 Gew. -% Silizium, 0,5 bis 2,0, bevorzugt 0,6 bis 1,5 Gew.-% Mangan, max. 0,2, bevorzugt 0,1 bis 0,2 Gew.-% Titan und max. 0,15, bevorzugt max. 0,1 Gew.-% Eisen enthält und bereits im Rheogefügezustand vorliegt.EP-B-0 792 380 describes an alloy which contains 3.0 to 6.0, preferably 4.6 to 5.8,% by weight of magnesium, 1.4 to 3.5, preferably 2.0 to 2, 8% by weight of silicon, 0.5 to 2.0, preferably 0.6 to 1.5% by weight of manganese, max. 0.2, preferably 0.1 to 0.2 wt .-% titanium and max. 0.15, preferably max. Contains 0.1 wt .-% iron and is already in Rheogefügezustand.
Diese bekannten AlMgSi-Legierungen sind für die Verwendung in Druckgußverfahren und damit verwandten Verfahren vorgesehen. Sie besitzen bereits im Gußzustand ähnliche Festigkeits- und Dehnungswerte wie AlSiMg-Legierungen, z.B. die bekannte Legierung vom Typ AlSi7MgO,3, im vollausgehärteten Zustand (welcher als "T6" bezeichnet wird) . Ein wesentlicher Nachteil dieser AlMgSi-Legierungstypen ist jedoch die - verglichen mit AlSiMg- Legierungen - geringere 0, 2%-Dehngrenze. Die 0,2%-Dehngrenze charakterisiert den Übergang von der elastischen zur plastischen Verformung eines Gußteiles und ist insbesondere auch im Zusammenhang mit crashrelevanten Strukturteilen im Automobilbau von Relevanz. In der Literatur wird über die Möglichkeit einer kurzen, max. 2 Stunden dauernden, Wärmebehandlung zur Anhebung der 0,2%-Dehngrenze berichtet.These known AlMgSi alloys are intended for use in die casting and related processes. Already in the as-cast state, they have strength and elongation values similar to those of AlSiMg alloys, eg the well-known alloy AlSi7MgO, 3, in the fully cured state (which is referred to as "T6"). A major disadvantage of these AlMgSi alloy types, however, is the lower 0.2% yield strength compared to AlSiMg alloys. The 0.2% proof strength characterizes the transition from the elastic to the plastic deformation of a casting and is particularly relevant in connection with crash-relevant structural parts in the automotive industry. In the literature, the possibility of a short, max. 2 hour heat treatment reported to increase 0.2% proof stress.
Eine Wärmebehandlung von Druckgußteilen aus den oben angeführten AlMgSi-Legierungen bringt jedoch zahlreiche Nachteile mit sich. Zunächst wird dadurch der Kostenvorteil, welcher durch derartige Legierungen erzielt werden kann, zunichte gemacht. Weitere wesentliche Nachteile der Wärmebehandlung sind typische Fehler an Druckgußteilen wie Verzug und vor allem Blasen, welche durch thermische Zerstörung von eingeschlossenen Formtrennstoffen entstehen und unter dem Begriff "Blister" bekannt sind. Ein Verzug macht jedoch den Prozessvorteil von Druckgußteilen, nämlich die endabmessungsnahe Fertigung, zunichte .However, heat treatment of die-cast parts of the above-mentioned AlMgSi alloys involves numerous disadvantages. First, this eliminates the cost advantage that can be achieved by such alloys. Other significant disadvantages of the heat treatment are typical errors in die castings such as distortion and especially bubbles, which are caused by thermal destruction of trapped mold release agents and are known by the term "blister". However, a delay nullifies the process advantage of die-cast parts, namely the near-end production.
Bei Druckgußteilen, welche keiner Wärmebehandlung zur Er- höhung insbesondere der 0,2%-Dehngrenze unterworfen werden, wird als Folge der verhältnismäßig geringen 0,2%-Dehngrenze das Einsatzgebiet der vorstehend beschriebenen Aluminiumlegierungen eingeschränkt, da besonders bei belasteten Druckgußteilen höhere Festigkeitseigenschaften gefordert sind. Einem Einsatz von aus solchen Legierungen hergestellten Druckgußteilen kann dann nur durch eine Vergrößerung der Wandstärke begegnet werden. Die Vergrößerung der Wandstärke verringert jedoch einen durch den Einsatz von Aluminium erreichbaren Gewichtsvorteil oder macht diesen zunichte. Das Ziel der vorliegenden Erfindung besteht daher darin,In the case of die-cast parts which are not subjected to any heat treatment for increasing, in particular, the 0.2% proof strength, the field of application of the aluminum alloys described above is restricted as a result of the relatively low 0.2% proof strength, since higher strength properties are required, especially with loaded die-cast parts , An application of die castings produced from such alloys can then be counteracted only by increasing the wall thickness. Increasing the wall thickness, however, reduces or overcomes a weight advantage achievable by the use of aluminum. The object of the present invention is therefore to
Aluminiumlegierungen vom Typ AlMgSi bereitzustellen, welche für die Verwendung im Druckguß geeignet sind und im Vergleich zu den aus dem Stand der Technik bekannten Legierungen vergleichbare Festigkeitseigenschaften, jedoch höhere Werte hinsichtlich der 0,2%-Dehngrenze aufweisen. Ein weiteres Ziel der Erfindung besteht darin derartige Aluminiumlegierungen bereitzustellen, welche die gewünschten Festigkeitseigenschaften bereits im Gußzustand aufweisen, sodaß eine Wärmebehandlung von Druckgußteilen und die damit verbundenen Nachteile vermieden werden. Es ist ein weiteres Ziel der vorliegenden Erfindung Aluminiumlegierungen bereitzustellen, welche für Aluminiumkomponenten im Automobilbau, insbesondere auch solche, welche hohen mechanischen Anforderungen genügen müssen, verwendet werden können, um so das Anwendungsgebiet von Aluminiumkomponenten beispielsweise im Automobilbau zu erweitern.To provide aluminum alloys of the type AlMgSi, which are suitable for use in die casting and compared to the known from the prior art alloys comparable strength properties, but have higher values in terms of 0.2% proof stress. Another object of the invention is to provide such aluminum alloys, which have the desired strength properties already in the cast state, so that a heat treatment of die castings and the associated disadvantages are avoided. It is a further object of the present invention to provide aluminum alloys which can be used for automotive aluminum components, particularly those which are required to meet high mechanical requirements so as to broaden the field of application of aluminum components, for example in the automotive industry.
Diese Ziele werden erfindungsgemäß durch eine Legierung erreicht, welche die folgende Zusammensetzung besitzt: 4,5 bis 6,5 Gew.-% Magnesium, 1,0 bis 3,0 Gew.-% Silizium, 0,3 bis 1,0 Gew.-% Mangan, 0,02 bis 0,3 Gew.-% Chrom, 0,02 bis 0,2 Gew.-% Titan, 0,02 bis 0,2 Gew.-% Zirkonium,These objects are achieved according to the invention by an alloy having the following composition: 4.5 to 6.5 wt .-% magnesium, 1.0 to 3.0 wt .-% silicon, 0.3 to 1.0 wt. % Manganese, 0.02 to 0.3% by weight chromium, 0.02 to 0.2% by weight titanium, 0.02 to 0.2% by weight zirconium,
0,0050 bis 1,6 Gew.-% eines oder mehrerer Seltenerdmetalle, max. 0,2 Gew.-% Eisen und als Rest Aluminium.0.0050 to 1.6% by weight of one or more rare earth metals, max. 0.2 wt .-% iron and balance aluminum.
In einer weiteren Ausführungsform besitzt die erfindungs- gemäße Legierung die folgende Zusammensetzung:In a further embodiment, the alloy according to the invention has the following composition:
5,5 bis 6,5 Gew.-% Magnesium 2,4 bis 2,8 Gew. -% Silizium 0,4 bis 0,6 Gew.-% Mangan 0,05 bis 0,15 Gew.-% Chrom.5.5 to 6.5% by weight of magnesium 2.4 to 2.8% by weight of silicon 0.4 to 0.6% by weight of manganese 0.05 to 0.15% by weight of chromium.
In einer weiteren bevorzugten Ausführungsform der erfindungsgemäßen Legierung ist ein Zirkoniumgehalt von 0,05 bis 0,2 Gew.-% vorgesehen.In a further preferred embodiment of the alloy according to the invention a zirconium content of 0.05 to 0.2 wt .-% is provided.
Als Seltenerdmetalle sind Samarium, Cer oder Lanthan bevorzugt. Diese können allein oder in jedweder Kombination miteinander zulegiert werden. Besonders vorteilhaft sind Kombinationen aus Samarium und Cer oder Samariam und Lanthan. Eine be- sonders bevorzugte Legierung enthält die Seltenerdmetalle Sama- - A - riutn und Cer in einer Menge von 0,0050 bis 0,8 Gew.-% Samarium und 0,0050 bis 0,8 Gew.-% Cer.As rare earth metals, samarium, cerium or lanthanum are preferred. These can be alloyed alone or in any combination with each other. Particularly advantageous are combinations of samarium and cerium or samariam and lanthanum. A particularly preferred alloy contains the rare earth elements Sama- - A - riutn and cerium in an amount of 0.0050 to 0.8 wt .-% samarium and 0.0050 to 0.8 wt .-% cerium.
Die Zugabe von Samarium und Cer führt bei der Erstarrung der Legierung zur Bildung von Ausscheidungen des Typs AlCe und AlSm in unterschiedlichen Zusammensetzungen, welche einen Verfestigungseffekt bewirken.The addition of samarium and cerium leads to the formation of precipitates of the AlCe and AlSm type in different compositions which cause a solidification effect upon solidification of the alloy.
Durch die Zugabe von Cer wird zudem auch die Klebeneigung der Legierung im Druckgußwerkzeug vermindert, was sich auf die Qualität der Druckgußteile zusätzlich vorteilhaft auswirkt.The addition of cerium also reduces the sticking tendency of the alloy in the diecasting tool, which additionally has an advantageous effect on the quality of the diecasting parts.
Die vorliegende Erfindung wird an Hand der für die nachstehenden Legierungen ermittelten mechanischen Kennwerte weiter veranschaulicht. Die mechanischen Kennwerte wurden an mittels Druckguß hergestellten Stufenplatten im Zugversuch nach DIN EN 10002 ermittelt, wobei für den Zugversuch die 2,7 mm Stufe herangezogen wurde. Dieser Wandstärkenbereich wird bevorzugt zur Herstellung von schweißbaren und unter Umständen crashrelevanten Strukturteilen verwendet. Die mechanischen Kennwerte stellen den Mittelwert aus 25 Messungen dar.The present invention will be further illustrated with reference to the mechanical characteristics determined for the following alloys. The mechanical characteristics were determined on step plates produced by die casting in the tensile test according to DIN EN 10002, wherein the 2.7 mm step was used for the tensile test. This wall thickness range is preferably used for the production of weldable and possibly crashrelevanten structural parts. The mechanical characteristics represent the average of 25 measurements.
Die Ergebnisse der durchgeführten Zugversuche sind in der Tabelle 1 angeführt . Bei den darin angeführten Legierungen sind die Legierungen der Versuche 1 bis 4 erfindungsgemäß; bei der Referenzlegierung handelt es sich um eine Legierung, deren Zusammensetzung einer erfindungsgemäßen Legierung entspricht, jedoch keine Seltenerdmetalle zulegiert enthält.The results of the tensile tests performed are shown in Table 1. In the alloys listed therein, the alloys of Experiments 1 to 4 according to the invention; The reference alloy is an alloy whose composition corresponds to an alloy according to the invention, but does not contain any alloying with rare earth metals.
Tabelle 1Table 1
Wie aus der Tabelle ersichtlich ist, führt die Zugabe von Cer und Samarium im Vergleich zur unmodifizierten AlMg5Si2MnCr- Basislegierung zu einem signifikanten Anstieg der 0,2%-Dehn- grenze . Die mit den erfindungsgemäßen Aluminiumlegierungen erreichbaren Festigkeitswerte liegen zudem auf einem Niveau, welches mit Schmiedestücken aus AlSiIMgMn im Zustand T6, also nach einer Wärmebehandlung erreicht, wird. Aufgrund dessen und der gegenüber den bekannten Aluminiumlegierungen vom AlMgSi-Typ verbesserten 0 , 2%-Dehngrenze sind die erfindungsgemäßen Legierungen für neue Anwendungsgebiete, insbesondere zur Herstellung von hochbelasteten Aluminiumdruckgußteilen, wie sie vermehrt in der Automobilindustrie von Interesse sind, geeignet. As can be seen from the table, the addition of cerium and samarium leads to a significant increase in the 0.2% yield strength compared to the unmodified AlMg5Si2MnCr base alloy. The strength values achievable with the aluminum alloys according to the invention are also at a level which is achieved with forgings made of AlSiIMgMn in the state T6, that is to say after a heat treatment. Because of this and the improved compared to the known AlMgSi-type aluminum alloys 0, 2% proof strength alloys of the invention for new applications, in particular for the production of highly loaded aluminum die cast parts, as they are increasingly of interest in the automotive industry, suitable.
Ähnliche Ergebnisse hinsichtlich der mechanischen Festig- keitswerte können auch durch erfindungsgemäße Legierungen werden, worin Cer teilweise oder zur Gänze durch Lanthan ersetzt ist. Similar results in terms of mechanical strength values can also be obtained by alloys according to the invention in which cerium is replaced in whole or in part by lanthanum.
