Abstract
Description
Zur Herstellung von Zylinderköpfen werden meist AlSiMg-Legierungen verwendet. Diese und Varianten mit Kupfer, wie AlSi7MgCu0,5, weisen trotz hoher Ausgangsfestigkeit noch keine ausreichende Warmfestigkeit auf.to Production of cylinder heads are mostly AlSiMg alloys used. These and variants with copper, such as AlSi7MgCu0,5, exhibit despite high initial strength still no sufficient heat resistance on.
Aus
Wie sich gezeigt hat, lässt die Warmfestigkeit dieser mit Zirkon bzw. Hafnium modifizierten AlSi7Mg-Legierung jedoch auch noch zu wünschen übrig. Insbesondere bei zwängungsintensiven Zylinderkopfstrukturen kann eine geringe Warmfestigkeit/Alterungsbeständigkeit zum Ausfall über die thermomechanische Ermüdung führen.As has shown, lets the heat resistance of this zirconium or hafnium modified AlSi7Mg alloy but also to be desired. Especially in constraint-intensive Cylinder head structures can have low heat resistance / aging resistance to failure over the thermomechanical fatigue to lead.
Aufgabe der Erfindung ist es daher, eine korrosions- und rissfeste Aluminiumgusslegierung bereitzustellen, deren Warmfestigkeit gegenüber der bekannten mit Zirkon und/oder Hafnium modifizierten AlSi7Mg-Legierung wesentlich verbessert ist, jedoch mit einer so großen Bruchdehnung, dass jegliche Sprödigkeit oder Kerbempfindlichkeit ausgeschlossen ist.task The invention is therefore a corrosion and crack resistant cast aluminum alloy to provide their thermal stability compared to the known with zircon and / or hafnium modified AlSi7Mg alloy significantly improved is, but with such a big one Elongation at break, that any brittleness or notch sensitivity is excluded.

Dazu wurde die Bruchdehnung einer AlSi7Mg0,3-Legierung bestimmt, deren Kupfergehalt schrittweise von 0,01 auf 1,03 Gew.-% erhöht wurde.To the elongation at break of an AlSi7Mg0.3 alloy was determined, whose Copper content was gradually increased from 0.01 to 1.03 wt .-%.
Die
Legierungen wurden dabei, wie üblich, einer
T6-Wärmebehandlung
unterworfen, bestehend aus einem Lösungsglühen zwischen 470°C und 540°C, Wasserabschrecken
und eine Wärmeaushärtung bei
etwa 150°C
bis 200°C.

Mit anderen Worten: Die Erfindung beruht auf der Erkenntnis, dass die Warmfestigkeit einer AlSi7Mg-Legierung, die Sr und/oder Hf enthält, durch Cu noch erhöht werden kann, ohne dass eine Abnahme der Bruchdehnung zu befürchten ist.In other words, the invention is based on the finding that the heat resistance of an AlSi7Mg alloy containing Sr and / or Hf can be increased by Cu, without a decrease the elongation at break is to be feared.
Die aus der erfindungsgemäßen Legierung gegossenen Guss-Stücke werden vorzugsweise einer Wärmebehandlung, bestehend aus einem Lösungsglühen zwischen 470°C und 540°C, einem Abschrecken mit Wasser oder gegebenenfalls Luft und anschließend einem Warmaushärten für mehrere Stunden bei etwa 160°C bis 200°C unterworfen.The cast from the alloy according to the invention Become cast pieces preferably a heat treatment, consisting of a solution annealing between 470 ° C and 540 ° C, one Quenching with water or optionally with air and then one artificial aging for several hours at about 160 ° C up to 200 ° C subjected.
Die erfindungsgemäße Gusslegierung ist insbesondere für den Kokillenguss geeignet, vor allem von Motorkernbauteilen, insbesondere dem Motorblock, Zylinderkopf, Kurbelgehäuse und dergleichen Gussbauteilen, insbesondere in der Automobilindustrie. Aufgrund der hohen Streckgrenze und Bruchdehnung, die bei Arbeitstemperatur erhalten bleibt, ist sie insbesondere für zwängungssensitive Zylinderkopfstrukturen geeignet, also für Motoren mit eng benachbarten Brennräumen und eng bemessenen Ventilstegen.The Cast alloy according to the invention is especially for suitable for chill casting, especially of engine core components, in particular the engine block, cylinder head, crankcase and the like cast components, especially in the automotive industry. Due to the high yield strength and elongation at break, which is maintained at working temperature, is she especially for Cushion-sensitive cylinder head structures suitable, ie for Engines with closely spaced combustion chambers and narrow valve stems.
