Description

Die Erfindung betrifft ein Gussbauteil aus einer Aluminiumlegierung mit guter Warmfestigkeit.The invention relates to a cast component made of an aluminum alloy with good Temperature strength.

Für thermisch beanspruchte Bauteile werden heute üblicherweise AlSi-Legierungen eingesetzt, wobei die Warmfestigkeit durch Zulegieren von Cu erreicht wird. Kupfer erhöht allerdings auch die Warmrissneigung und wirkt sich negativ auf die Giessbarkeit aus. Anwendungen, bei denen insbesondere Warmfestigkeit gefordert wird, findet man Hauptsächlich im Bereich der Zylinderköpfe im Automobilbau, siehe z.B. F. J. Feikus, "Optimierung von Aluminium-Silicium-Gusslegierungen für Zylinderköpfe", Giesserei-Praxis, 1999, Heft 2, S. 50-57.For thermally stressed components today usually AlSi alloys used, wherein the heat resistance achieved by alloying of Cu becomes. However, copper also increases the tendency of hot cracking and has a negative effect on the castability. Applications where in particular heat resistance is required, one finds mainly in the field of cylinder heads in Automotive engineering, see e.g. F. J. Feikus, "Optimization of Aluminum-Silicon Casting Alloys for cylinder heads ", foundry practice, 1999, No. 2, pp. 50-57.

Die Giessbarkeit der Legierung sollte besser sein, als die der derzeit angewendeten AlSiCu-Gusslegierungen, und die Legierung sollte keine Tendenz zu Warmrissen zeigen.Due to the applications, the corrosion tendency of the alloy be kept as low as possible, and the alloy must also be an appropriate have good fatigue strength.

Feikus, "Optimierung von Aluminium-Silicium-Gusslegierungen für Zylinderköpfe", Giesserei-Praxis, 1999, Heft 2, S. 50-57 mit den in Tabelle 1 angegebenen Zusammensetzungen wurden hinsichtlich ihres Langzeitverhaltens unter Dauertemperaturbelastung miteinander verglichen.

Die erfindungsgemässe Legierung wurde in einer Probestabkokille nach Diez zu Rundstäben von 16 mm Durchmesser vergossen. An den Probestäben wurden die mechanischen Eigenschaften Dehngrenze (Rp0.2), Zugfestigkeit (Rm) und Bruchdehnung (A5) im Zustand T6 (165 °C / 6h) nach einer Dauertemperaturbelastung von 500 h bei verschiedenen Temperaturen bestimmt. Die entsprechenden Werte für die Vergleichslegierung wurden dem obigen Artikel von F. J. Feikus entnommen. Die Ergebnisse sind in Fig. 1 in Diagrammform dargestellt.The inventive alloy was in a sample mold according to Diez cast into round rods of 16 mm diameter. At the test bars were the mechanical properties yield strength (Rp0.2), tensile strength (Rm) and elongation at break (A5) in condition T6 (165 ° C / 6h) after a constant temperature load determined from 500 h at different temperatures. The corresponding Values for the comparative alloy were from the above article of Taken from F. Feikus. The results are shown in Fig. 1 in diagram form.

Die erfindungsgemässe Legierung AlMg3Si1MnCr erreicht zwar hinsichtlich der Dehngrenze und der Zugfestigkeit nicht die Spitzenwerte der Vergleichslegierung AlSi7MgCu1, ist aber in ihrem Temperaturverhalten "weniger wechselhaft". Diese Wechselhaftigkeit drückt sich im Betrieb insofern störend aus, als geringe Änderungen der Temperatur große Veränderungen der mechanischen Eigenschaften verursachen können. Die Streckgrenze der erfindungsgemässen Legierung bleibt bis etwa 180 °C auf einem nahezu gleichen Niveau, fällt bis 200 °C allmählich ab und beginnt erst ab ca. 200 °C kontinuierlich abzufallen. Der kontinuierliche Abfall geschieht im Vergleich zur Legierung AlSi7MgCu1 mit geringerer Neigung.Although the alloy AlMg3Si1MnCr according to the invention achieves the same Yield strength and tensile strength are not the peak values of the comparative alloy AlSi7MgCu1, but is "less changeable" in its temperature behavior. This changeability expresses itself disturbing in operation, as low Changes in temperature great changes in mechanical properties can cause. The yield strength of the alloy according to the invention remains at about 180 ° C at a nearly same level, drops to 200 ° C gradually and begins to fall only from about 200 ° C continuously. Of the continuous waste occurs in comparison to the alloy AlSi7MgCu1 with lower Tilt.

Hinsichtlich der Bruchdehnung zeichnet sich die erfindungsgemässe Legierung durch einen nahezu konstanten Wert bis 180 °C aus. Hohe Dehnungswerte liefern ein günstiges Bruch-/ Versagensverhalten. Dem Bruch des Bauteils geht eine sichtbare Verformung voraus. Oberhalb 180 °C steigt die Dehnung kontinuierlich an. Bei der Vergleichslegierung AlSi7MgCu1 erkennt man hier den deutlichen Aushärtungseffekt. Niedrige Dehnungswerte bewirken ein ungünstiges Versagensverhalten, d.h. das Bauteil verformt sich nur geringfügig oder gar nicht. Bei Belastungsspitzen bricht das Bauteil ohne Vorwarnung.With regard to the elongation at break, the alloy according to the invention is distinguished by a nearly constant value up to 180 ° C from. High elongation values deliver a favorable fracture / failure behavior. The break of the component goes a visible deformation ahead. Above 180 ° C, the strain increases continuously at. In the case of the comparison alloy AlSi7MgCu1, one recognizes the clear curing effect. Low elongation values cause an unfavorable Failure behavior, i. the component deforms only slightly or even Not. At load peaks, the component breaks without warning.
