Description

Magnesiumlegierung Zusatz zum Patent 700 517 Gegenstand der Erfindung ist die weitere Ausbildung des Patents 700517.Magnesium alloy addition to patent 700,517 subject of the invention is the further development of the patent 700517.

Das Hauptpatent betrifft eine vergütbare, aluminiumhaltige Magnesiumlegierung, die 8 bis I4% Aluminium und 4 bis I4% Wismut, Rest Magnesium, enthält. Es wurde gefunden, daß derart hohe mechanische Eigenschaften sowie brauchbare Korrosionsbeständigkeit, wie sie die Legierungen. nach dem Hauptpatent aufweisen, auch dann erhalten werden können, wenn der Aluminiumgehalt weniger als 8% beträgt. Als unterste Grenze für den Gehalt an Aluminium in den neuen Legierungen hat sich dabei der Prozentsatz von 0,05 als günstig erwiesen. Gleichzeitig wurde gefunden, daß zur Erreichung der geschilderten Eigenschaften ein Wismutgehalt genügt, der nur mehr als 2% zu betragen braucht.The main patent relates to a heat treatable, aluminum-containing magnesium alloy, which contains 8 to 14% aluminum and 4 to 14% bismuth, the remainder being magnesium. It was found that such high mechanical properties and useful corrosion resistance, as they do the alloys. according to the main patent, can then also be obtained can if the aluminum content is less than 8%. As the lowest limit for the percentage of aluminum in the new alloys has increased of 0.05 proved to be beneficial. At the same time it was found that to achieve the A bismuth content of only more than 2% is sufficient for the properties described needs.

Die vorliegende Erfindung betrifft somit eine Magnesiumlegierung, die o,o5 bis weniger als 8% Aluminium und mehr als 2, aber nicht über I4% Wismut, Rest Magnesium, enthält.The present invention thus relates to a magnesium alloy, the o, o5 to less than 8% aluminum and more than 2, but not over 14% bismuth, The remainder of magnesium.

Aluminium-wismuthaltige Magnesiumlegierungen mit Wismutgehalten bis 2"[o sind bereits bekannt. Durch die Steigerung des Wismutgehaltes über 20/, wurde jedoch eine überraschende Erhöhung der .mechanischen Eigenschaften erhalten. Diese ergibt sich aus den Vergleichsversuchen, die mit den bekannten und neuen aluminium-wismuthaltiben Magnesiumlegierungen angestellt wurden. Es wurden Magnesiumlegierungen der folgenden Zusammensetzungen untersucht: Lfde.Nr. Aluminium Wismut Magnesium I 3 0,5 Rest 2 2 I - 3 4 2 - 4 5 8 - 5 4 5 - b 7 12 - Die Vergleichsversuche erstreckten sich auf Feststellung der Zugfestigkeit und Dehnung der verpreßten, vergüteten Legierungen. Sie hatten die folgenden Ergebnisse: Lfde. Nr. kg mm² I0% I 32 7 2 32,5 5 3 34 4 4 44,5 4 5 43,5 5 6 47 3 Als weiteres vorteilhaftes Beispiel gemäß der vorliegenden Erfindung ist eine Magnesiumlegierung zu nennen, die eine Zusammensetzung von 6,5% Aluminium und 5% Wismut, Rest Magnesium, besitzt.Aluminum-bismuth-containing magnesium alloys with bismuth contents of up to 2 "[o are already known. By increasing the bismuth content over 20 /, however, a surprising increase in the mechanical properties was obtained. Magnesium alloys containing bismuth were employed. Magnesium alloys of the following compositions were investigated: No. Aluminum bismuth magnesium I 3 0.5 remainder 2 2 I - 3 4 2 - 4 5 8 - 5 4 5 - b 7 12 - The comparative tests extended to determining the tensile strength and elongation of the pressed, tempered alloys. They had the following results: Lfde. No. kg mm² I0% I 32 7 2 32.5 5 3 34 4 4 44.5 4 5 43.5 5 6 47 3 A further advantageous example according to the present invention is a magnesium alloy which has a composition of 6.5% aluminum and 5% bismuth, the remainder being magnesium.

Zu den neuen Legierungen können noch unter entsprechender Verringerung des Magnesiumgehaltes, bei Einhaltung der genannten Mengen an Aluminium und Wismut, je o,I bis 2% Calcium. Mangan, Silicium, eines der Metalle der Eisengruppe (Eisen, Nickel, Kobalt) einzeln oder zu mehreren zugesetzt werden.The new alloys can still be reduced accordingly the magnesium content, if the specified amounts of aluminum and bismuth are adhered to, 0.1 to 2% calcium each. Manganese, silicon, one of the metals of the iron group (iron, Nickel, cobalt) can be added individually or in groups.
