Verfahren zur Erhöhung der Korrosionsfestigkeit von Legierungen des Aluminiums mit etwa 3 bis 16% Magnesium.
EMI1.1
<Desc/Clms Page number 2>
In Fällen, in denen die Wärmebehandlung gemäss vorliegender Erfindung vor einer Kaltverarbeitung der Legierungen erfolgt, kann anschliessend an diese letztere eine Glühung bei Temperaturen unterhalb derjenigen vorgenommen werden, bei der bei gleicher Glühdauer Rekristallisation eintritt.
PATENT-ANSPRÜCHE :
1. Verfahren zur Erhöhung der Korrosionsfestigkeit von Legierungen des Aluminiums mit etwa 3-16% Magnesium, gegebenenfalls in Gegenwart von untergeordneten Mengen weiterer Legierungmetalle, wie insbesondere zwischen 0-1 und 2% Mangan, dadurch gekennzeichnet, dass zunächst ein mehr oder weniger homogenes Gefüge durch Glühung bei Temperaturen zwischen dem Soliduspunkt und demjenigen Temperaturgebiet, in dem die Veränderlichkeit der Löslichkeit des Magnesiums in festem Zustand nennenswerte Beträge annimmt, hergestellt wird, worauf sich, gegebenenfalls nach vorheriger Abschreckung, eine Anlassbehandlung bei Temperaturen unterhalb des genannten Temperaturgebietes anschliesst,
durch die eine Wiederausscheidung von in homogene feste Lösung übergeführten Anteilen des Magnesiums in fein verteilter Form herbeigeführt wird.

Process for increasing the corrosion resistance of alloys of aluminum with about 3 to 16% magnesium.
EMI1.1
<Desc / Clms Page number 2>
In cases in which the heat treatment according to the present invention takes place prior to cold processing of the alloys, the latter can be followed by annealing at temperatures below that at which recrystallization occurs for the same annealing time.
PATENT CLAIMS:
1. A method for increasing the corrosion resistance of alloys of aluminum with about 3-16% magnesium, optionally in the presence of minor amounts of other alloy metals, such as in particular between 0-1 and 2% manganese, characterized in that initially a more or less homogeneous structure by annealing at temperatures between the solidus point and that temperature range in which the variability of the solubility of the magnesium in the solid state assumes significant amounts, which, if necessary after previous quenching, is followed by a tempering treatment at temperatures below the specified temperature range,
through which a re-excretion of parts of the magnesium converted into homogeneous solid solution is brought about in finely divided form.
