Description
Vorliegende Erfindung betrifft die Verwendung von AlMgSi-Guß-Legierungen, bestehend aus 0,6 bis 4,5% Silizium, 2,5 bis 11% Magnesium, mit der Maßgabe, daß im Rahmen der angegebenen Bereiche das Verhältnis von Magnesium zu Silizium so aufeinander abgestimmt ist, daß 1 bis 4,5% Magnesium nicht an Silizium gebunden vorliegen, 0,6 bis 1,8% Mangan, Rest Aluminium mit den üblichen herstellungsbedingten Verunreinigungen, sowie bis zu 0,6% Kupfer als zulässige Beimengung, als hochfester, im Bestandteil Mg2Si gefeinter Werkstoff für thermisch wechselbeanspruchte Zylinderköpfe, die bei einer thermischen 40The present invention relates to the use of AlMgSi cast alloys, consisting of 0.6 to 4.5% silicon, 2.5 to 11% magnesium, with the proviso that within the specified ranges the ratio of magnesium to silicon is so one on top of the other it is agreed that 1 to 4.5% magnesium is not bound to silicon, 0.6 to 1.8% manganese, the remainder aluminum with the usual production-related impurities, as well as up to 0.6% copper as a permissible admixture, as a high-strength, Material refined in the component Mg 2 Si for cylinder heads subject to alternating thermal loads, which at a thermal 40

35 Wechselbeanspruchung zwischen 100 bis 3000C binnen 120 Sekunden mehr als 1050 Lastwechsel bis zum Durchriß aushalten und gut bearbeitbar sein müssen, nach Patent Nr. 14 83 229. 35 Alternating loads between 100 and 300 0 C within 120 seconds must withstand more than 1050 load changes up to the point of opening and must be easy to work with, according to patent no. 14 83 229.
Aufgabe vorliegender Erfindung ist es, bei der Herstellung von Zylinderköpfen im Rahmen der im Hauptpatent angegebenen Verwendung die mechanischen Werte und die Rißbeständigkeit insbesondere der jeweils gefährdeten bzw. hochbeanspruchten Partien der Zylinderköpfe zu verbessern. Dies wird dadurch erreicht, daß beim Guß die jeweils besonders gefährdeten bzw. hochbeanspruchten Partien der Zylinderköpfe während der Erstarrung durch zusätzliches Kühlen einer schnelleren Abkühlung unterworfen worden sind als die übrigen Partien der Zylinderköpfe.The object of the present invention is, in the production of cylinder heads in the context of the im Main patent specified the mechanical values and the crack resistance, in particular the use to improve endangered or highly stressed areas of the cylinder heads. This is because of this achieved that during casting, the particularly endangered or highly stressed parts of the cylinder heads have been subjected to more rapid cooling during the solidification by additional cooling than the remaining parts of the cylinder heads.
Hierdurch wird die gestellte Aufgabe in hervorragendem Maße gelöst. So z. B. erreichten Zylinderköpfe aus einer Legierung mit 0,9% Mangan, 4,4% Magnesium, 1,0% Silizium, 0,004% Beryllium, Rest Aluminium und übliche Verunreinigungen eine thermische Wechselbelastungszahl von 1550 Lastwechseln bis zum Riß der mit 3,5 1 H2O schneller gekühlten Stegpartie.This solves the problem posed to an excellent degree. So z. B. achieved cylinder heads made of an alloy with 0.9% manganese, 4.4% magnesium, 1.0% silicon, 0.004% beryllium, the remainder aluminum and usual impurities a thermal alternating load number of 1550 load changes up to the crack of 3.5 1 H 2 O more quickly cooled bridge area.
Zylinderköpfe aus einer Legierung mit 0,85% Mangan, 4,0% Magnesium, 1,2% Silizium, 0,004% Beryllium und Rest Aluminium und üblichen Verunreinigungen, die einer Kühlung mit 13 1 H2O der Kokille im Kalottengebiet unterworfen wurden, hielten thermische Wechselbelastungsversuche mit einer Wechselbelastungszahl von 2220 aus.Cylinder heads made of an alloy with 0.85% manganese, 4.0% magnesium, 1.2% silicon, 0.004% beryllium and the remainder aluminum and usual impurities, which were subjected to cooling with 13 1 H 2 O of the mold in the dome area, held thermal alternating load tests with an alternating load number of 2220.
Auch die Zerreißfestigkeitswerte waren, wie die nachstehende Tabelle für letztere Legierung beispielsweise erweist, ausgezeichnet:Also the tensile strength values were like the table below for the latter alloy for example proves excellent:
Thermische Wechselbelastung: 2220
Mechanische WerteThermal alternating load: 2220
