Description

Verfahren zur Veredelung von Aluminium-Zink-Legierungen Im Hauptpatent 445 714 ist ein Verfahren beschrieben zur Veredelung von Aluminium-Zink-Legierungen, denen Magnesium in solchen Mengen zulegiert wird, daß es sich mit Zink restlos zu der Verbindung MgZn.; umsetzt, wobei Zusätze anderer Mischkristallbildner, wie z. B. Beryllium, Silicium, Kupfer u. a., nicht nur den Veredelungsvorgang nicht stören, sondern eine weitere Veredelung bewirken. Die Veredelung dieser Legierungen soll durch geeignete thermische und Alterungsbehandlungen bewirkt werden.Process for the finishing of aluminum-zinc alloys In the main patent 445 714 describes a process for refining aluminum-zinc alloys, to which magnesium is added in such quantities that it becomes completely with zinc the compound MgZn .; converts, with additions of other mixed crystal formers, such as. B. beryllium, silicon, copper and others, not only do not interfere with the refining process, but cause a further refinement. The refinement of these alloys is supposed to be effected by suitable thermal and aging treatments.

Es hat sich nun gezeigt, daß eine sehr wesentliche weitere Veredelung erzielt wird, wenn nach Ausglühen und Abschrecken die Lagerung zum Zwecke der Selbstvergütung bei höheren Temperaturen ausgeführt wird. Dies gilt ganz besonders für Legierungen, die einen größeren Gehalt an MgZn2 aufweisen. Die Lagerung bei höheren Temperaturen kann sofort nach dem Abschrecken nach einer Zwischenlagerung bei Zimmertemperatur oder auch nach dem völligen Auslagern der Legierung bei Zimmertemperatur erfolgen. Man hat es 'hierbei in der Hand, je nach W;unf&lch Legierungen von verschiedenen Festigkeiten und Dehnungen zu erhalten. Höchstwerte der Festigkeit erhält man, wenn nach Auslagereng der Legierungen bei Zimmertemperatur (etwa 5 bis 8 Tage) diese. einer weiteren Nachlagerung bei höheren Temperaturen. ausgesetzt werden. Auch hat man es in der Hand, durch geeignete Wahl der Lagerungstemperatur einen Werkstoff von verschiedenen Festigkeiten und Dehnungen zu erhalten. Selbstredend ist jeweils, entsprechend der Zusammensetzung der Legierungen,, die günstigste Temperatur und Dauer der Lagerung durch praktische Versuche zu ermitteln. Im allgemeinen kann gesagt werden, daß diese Temperaturen zwischen 5o und 15o° liegen, die Lagerungsdauer zwischen 3 und 48 Stunden.It has now been shown that a very substantial further refinement is achieved if, after annealing and quenching, storage for the purpose of self-remuneration run at higher temperatures. This is especially true for alloys, which have a higher content of MgZn2. Storage at higher temperatures can be used immediately after quenching after intermediate storage at room temperature or after the alloy has been completely aged at room temperature. You have it in your hand, depending on the type of material and alloys of different types To maintain strength and elongation. Maximum strength values are obtained when after the alloys have been stored at room temperature (about 5 to 8 days). a further post-storage at higher temperatures. get abandoned. Also has you have it in hand, by choosing a suitable storage temperature for a material of different strengths and elongations. It goes without saying that according to the composition of the alloys ,, the most favorable temperature and The duration of storage can be determined through practical tests. In general it can be said be that these temperatures are between 5o and 15o °, the storage time between 3 and 48 hours.

Eine weitere Verfestigung dieser Legi,e;-rungen wird erzielt, wenn ihnen, was an sich bekannt ist, geringe Mengen hochschmelzender Komponenten, z. B. Nickel, Titan, Wolfram, Molybdän u. dgl. zugesetzt werden. Die Zusatzmenge dieser Komponenten darf nicht mehr als etwa I % betragen, da andernfalls die Bearbeitbarkeit der Legierungen sehr erschwert wird.A further consolidation of these legi, e; -rungen is achieved if them, which is known per se, small amounts of high-melting components, e.g. B. nickel, titanium, tungsten, molybdenum and the like. Can be added. The additional amount of this Components must not be more than about 1%, otherwise the machinability the alloys is very difficult.
