In einer weiteren Ausführungsform enthält die erfindungsgemässe Legierung 0,3 bis 0,4 Gew.-% Magnesium.In a further embodiment, the alloy according to the invention contains from 0.3 to 0.4% by weight of magnesium.
Bevorzugt wird die erfindungsgemässe Druckgusslegierung zum Druckgiessen crashrelevanter oder festigkeitsrelevanter Strukturteilen im Automobilbau eingesetzt.The diecasting alloy according to the invention is preferably used for pressure casting of crash-relevant or strength-relevant structural parts in the automotive industry.
Die geeignete Festigkeit einer Aluminium-Druckgusslegierung wird neben der Wahl der Kombination an Legierungselementen auch durch eine gezielte Wärmebehandlung erreicht. Die erfindungsgemässe Legierung wird einer T6-Wärmebehandlung umfassend Lösungsglühen, Luftabschreckung oder Wasserabschreckung und Warmauslagerung unterzogen. Dabei konnte festgestellt werden, dass verglichen mit der Legierung aus
Die erfindungsgemässe Legierung ist nach der T6-Wärmebehandlung zeitfest, d.h. es tritt keine Selbstaushärtung ein.The alloy according to the invention is time-stable after T6 heat treatment, i. there is no self-curing.
Ferner ist es möglich, durch eine T6-Wärmebehandlung bei Anwendung hoher Glühtemperaturen von 530°C Dehngrenzen von bis zu 280 N/mm2 zu erreichen, in dem anschliessend eine Wasserabschreckung erfolgt.Furthermore, it is possible to achieve by a T6 heat treatment with application of high annealing temperatures of 530 ° C Dehngrenzen of up to 280 N / mm 2 , in which then a water quenching takes place.
Ferner kann die erfindungsgemässe Legierung einer T7-Wärmebehandlung unterzogen sein.Furthermore, the alloy according to the invention may be subjected to a T7 heat treatment.
Mit der erfindungsgemässen Legierungszusammensetzung lassen sich bei Druckgussteilen im Werkstoffzustand T6 bzw. T7 verbesserte Werte für Zugfestigkeit, die Dehngrenze und die Bruchdehnung erzielen.With the alloy composition according to the invention, it is possible to achieve improved values for tensile strength, the yield strength and the elongation at break in die cast parts in the material state T6 or T7.
Verglichen mit der Legierung aus
Wird gleichzeitig Molybdän zugegeben, wirken diese beiden Elemente zusammen und es wird zusätzlich eine Steigerung der Festigkeit erreicht. Eine Erhöhung dieser Elemente über 0,2 % hinaus hat keine positive Wirkung auf die Kennwerte des Werkstoffs.If molybdenum is added at the same time, these two elements act together and, in addition, an increase in strength is achieved. Increasing these elements beyond 0.2% has no positive effect on the characteristics of the material.
Eine ähnliche Wirkung zeigte die Zugabe von Gallium auf die erfindungsgemäße Legierung. Mit der Zugabe von Gallium, neben Zirkon und Molybdän, konnte ein feineres Gefüge erreicht werden, insbesondere bei leicht erhöhtem Eisengehalt.A similar effect was shown by the addition of gallium to the alloy according to the invention. With the addition of gallium, in addition to zirconium and molybdenum, a finer structure could be achieved, especially with slightly increased iron content.
Die Zugabe von Mo, Zr und Ga spielt eine besondere Rolle, wenn Recyclingmaterial, sprich Sekundäraluminium zur Herstellung der Legierung, verwendet wird. Bei einem Eisengehalt von 0,2 % ist es möglich, die schädliche Wirkung des Eisens auf die Bruchdehnung zu minimieren. Es entsteht ein deutlich feineres Gefüge, in dem AlMgFeSi-Phasen kleiner und gleichmäßiger verteilt sind.The addition of Mo, Zr and Ga plays a special role when recycling material, that is secondary aluminum, is used to produce the alloy. With an iron content of 0.2%, it is possible to minimize the harmful effect of iron on the elongation at break. This results in a much finer microstructure in which AlMgFeSi phases are smaller and more evenly distributed.
Dem leicht erhöhten Eisengehalt wird durch eine Senkung des Mangananteils Rechnung getragen, ansonsten besteht die Gefahr von Schlammbildung im Warmhalteofen an der Gießmaschine. Die Klebeneigung der Legierung sinkt dennoch, da hierbei Eisen ebenso wie Mangan positiv wirkt und die Reduktion von Mn durch den Fe-Gehalt überkompensiert wird.The slightly increased iron content is taken into account by a reduction in the manganese content, otherwise there is a risk of sludge formation in the holding furnace at the casting machine. However, the tendency of the alloy to adhere decreases, since both iron and manganese have a positive effect and the reduction of Mn is more than compensated for by the Fe content.
Zudem wird durch das MnFe-Verhältnis die Entstehung von sog. Betaphasen vermieden, also plattenförmingen AlMnFeSi-Ausscheidungen, wodurch die Duktilität des Werkstoffs entscheidend reduziert wird. Solche Ausscheidungen sind unter dem Mikroskop als sog. Eisennadeln bekannt.In addition, the MnFe ratio prevents the formation of so-called beta phases, ie plate-shaped AlMnFeSi precipitates, which significantly reduces the ductility of the material. Such excretions are known under the microscope as so-called. Iron needles.
Die Alpha-AlMnFeSi-Ausscheidungen werden bei der erfindungsgemässen Legierung durch die Zugabe der Elemente Mo, Zr und Ga sehr fein ausgebildet, sodass ihre schädliche Wirkung auf Dehnwerte und Korrosionsneigung minimiert werden kann.The alpha-AlMnFeSi precipitates are formed very finely in the inventive alloy by the addition of the elements Mo, Zr and Ga, so that their harmful effect on Dehnwerte and corrosion tendency can be minimized.
Durch den gewählten, geringen Anteil an Zink in Verbindung mit den anderen, erfindungsgemässen Elementen wurden eine Verbesserung der Gießbarkeit und eine Erhöhung der Bruchdehnung erreicht. Im Allgemeinen zeigt ein Zinkgehalt von bis zu 0.5 Gew. % noch keine Wirkung auf Werkstoffkennwerte. Die gegenüber Patent
Die Zugabe von Strontium oder Natrium führt zu einer feinkristallinen Ausscheidung des Siliziums, was die Ausbildung eines veredelten Eutektikums zur Folge, und ebenfalls einen positiven Einfluss auf die Festigkeit und Dehnung der erfindungsgemässen Legierung hat.The addition of strontium or sodium leads to a finely crystalline precipitation of the silicon, which results in the formation of a refined eutectic, and also has a positive influence on the strength and elongation of the inventive alloy.
Bevorzugt wird bei der erfindungsgemässen Legierung eine Kornfeinung durchgeführt. Hierzu kann der Legierung vorzugsweise 1 bis 30 ppm Phosphor zugeführt werden. Alternativ oder zusätzlich kann die Legierung zur Kornfeinung auch Titan und Bor enthalten, wobei die Zugabe von Titan und Bor über eine Vorlegierung mit 1 bis 2 Gew.-% Ti und 1 bis 2 Gew.-% B, Restaluminium, erfolgt. Bevorzugt enthält die Aluminium-Vorlegierung 1,3 bis 1,8 Gew.-% Ti und 1,3 bis 1,8 Gew.-% B und weist ein Ti/B Gewichtsverhältnis von etwa 0,8 bis 1,2 auf. Der Gehalt der Vorlegierung in der erfindungsgemässen Legierung wird bevorzugt auf 0,05 bis 0,5 Gew.-% eingestellt.Grain refining is preferably carried out in the case of the alloy according to the invention. For this, the alloy may preferably be supplied with 1 to 30 ppm of phosphorus. Alternatively or additionally, the alloy may also contain titanium and boron for grain refining, the addition of titanium and boron via a master alloy with 1 to 2% by weight of Ti and 1 to 2% by weight of B, residual aluminum. Preferably, the aluminum master alloy contains 1.3 to 1.8% by weight of Ti and 1.3 to 1.8% by weight of B, and has a Ti / B weight ratio of about 0.8 to 1.2. Of the Content of the master alloy in the alloy according to the invention is preferably adjusted to 0.05 to 0.5 wt .-%.
Im Rahmen der Untersuchungen war es möglich, die erfindungsgemässe Legierung mit einem Recyclinganteil von 50-70 % herzustellen.Within the framework of the investigations it was possible to produce the alloy according to the invention with a recycling proportion of 50-70%.
Notwendig hierfür ist hochwertiges Recyclingmaterial, wie beispielsweise Schrotte von Rädern, Strangpressprofilen, Blechen und auch Spänen sowie die Verwendung eines bewährten Kipp-Trommelofens zum Schmelzen der Legierung. Bis zu einem Eisengehalt von 0,25 % konnten die Anforderungen an crashrelevante Strukturbauteile erfüllt werden, bis zu einem Eisengehalt von 0,40 % war ein Einsatz in festigkeitsrelevanten Strukturbauteilen möglich.Necessary for this is high-quality recycling material, such as scrap of wheels, extruded profiles, sheets and chips as well as the use of a proven tilting drum furnace for melting the alloy. Up to an iron content of 0.25%, the requirements for crash-relevant structural components could be fulfilled; up to an iron content of 0.40%, it was possible to use them in structural components relevant to structural strength.
Die Schweisseignung konnte in WIG-Schweißtests überprüft werden. In Stanznietversuchen war die erfindungsgemäße Legierung trotz ihrer hohen Festigkeit rissfrei nietbar.The weldability could be checked in TIG welding tests. In punch rivet tests, the alloy according to the invention was rivet free of cracks despite its high strength.
