Description

Nach Patent 417 773 veredelte Legierungen des Aluminiums mit einem höheren Siliziumgehalt Durch Patent 41,7 773 sind Aluminiumlegierungen für konstruktive und andere, insbesondere Gußzwecke, mit einem Siliziumgehalt bis zu 2o % geschützt, deren Kennzeichen darin besteht, daß ihre Struktur ohne mechanische Bearbeitung, wie Walzen, Ziehen, Hämmern u. dgl., durch einen nicht mechanischen Veredelungsvorgang feinkörnig gemacht ist, wodurch die Legierungen eine Dehnung über 3 % und höhere Festigkeitseigenschaften erhalten, als diejenigen gleichprozentiger, unveredelter, also noch gröber kristallinischer Aluminium -Silizium - Legierungen.Alloys of aluminum refined according to patent 417 773 with a higher silicon content By patent 41.7 773, aluminum alloys are used for constructive and others, especially casting purposes, protected with a silicon content of up to 2o%, which is characterized by the fact that its structure without mechanical processing, such as rolling, drawing, hammering and the like, by a non-mechanical finishing process is made fine-grained, giving the alloys an elongation of over 3% and higher Maintained strength properties than those of equal percentage, unrefined, So even coarser crystalline aluminum-silicon alloys.

Es wurde nun gefunden, daß, diese sogenannten veredelten Aluminium-Silizium-Legierungen-bei Zusatz von gewissen Metallen ihre guten mechanischen Eigenschaften nicht nur behalten, sondern noch weiter steigern können, sa daß auch die neuen Legierungen die Eigenschaften der normalen, binären Legierungen von Aluminium und Silizium übertreffen. Beispielsweise wurde mit veredelten Aluminiumlegierungen, die außer 13 % Silizium noch 2 % Kupfer oder 1 % Zink oder 1 % Cadmium oder 1 O;'o Antimon enthielten, Werte von 2o kg pro Quadratmillimeter und 5 % Dehnung ermittelt. Die Zusatzstoffe können entweder einzeln oder mehrere gleichzeitig im festen oder flüssigen Zustand :der betreffenden Aluminium-Silizium-Legierung zugegeben oder durch Umsetzung in sie eingeführt werden.It has now been found that these so-called refined aluminum-silicon alloys-in Addition of certain metals not only retain their good mechanical properties, The new alloys can also improve their properties even further the normal, binary alloys of aluminum and silicon. For example was made with refined aluminum alloys, which apart from 13% silicon also contain 2% copper or 1% zinc or 1% cadmium or 10% antimony, values of 20 kg per Square millimeters and 5% elongation determined. The additives can either be used individually or several at the same time in the solid or liquid state: the relevant aluminum-silicon alloy added or introduced into them by reaction.

Außerdem konnte festgestellt werden, daß durch eine geeignete Wärmebehandlung sich noch weitere Steigerungen der mechanischen Eigenschaften dieser Legierungen herbeiführen lassen. Zu diesem Zweck werden die fertigen Gußstücke oder Werkstücke vor oder nach der Verarbeitung, z. B. durch Pressen, Walzen, Ziehen u. dgl., auf Temperaturen oberhalb 1 oö erhitzt und entweder an -der Luft abgekühlt oder im Wasser abgeschreckt. Auch können sie noch einer Lagerung unter bekannten Temperaturbedingungen unterzogen werden. Dieser Proz@eß kann auch öfter wiederholt werden. Bemerkt sei, daß die thermische Behandlung in Anwendung auf andere Legierungen bekannt ist.In addition, it was found that through a suitable heat treatment There are further increases in the mechanical properties of these alloys let bring about. The finished castings or workpieces are used for this purpose before or after processing, e.g. B. by pressing, rolling, pulling and the like Temperatures above 1 oö heated and either cooled in air or in water deterred. They can also be stored under known temperature conditions be subjected. This process can be repeated more often. It should be noted that thermal treatment is known to be applied to other alloys.
