  Vergütbare Magnesiumlegierung mit Gehalten an Aluminium und Wismut. 



   Die vorliegende Erfindung betrifft eine thermisch vergütbare Magnesiumlegierung hoher Festigkeit, die sich als Werkstoff im Fahrzeug-und Flugzeugbau dort mit Vorteil verwenden lässt, wo es auf hohe Festigkeit und möglichst geringes Gewicht ankommt. Die erfindungsgemässe Legierung weist Gehalte an Aluminium und Wismut auf. 



   Eine aluminiumhaltige Magnesiumlegierung mit Zusätzen an Antimon und/oder Wismut ist bereits bekannt, jedoch soll bei dieser Legierung der Gehalt an den Metallen Antimon oder Wismut oder beiden den Betrag von höchstens   2%   zweckmässig nicht überschreiten. 



   Im Gegensatz dazu enthält die Magnesiumlegierung gemäss der vorliegenden Erfindung neben 8-14% Aluminium einen Betrag von 4 bis 14% Wismut. Die Steigerung des Wismutgehaltes ergibt eine   überraschende   Erhöhung der mechanischen Eigenschaften. Als zweckmässiger unterer Gehalt 
 EMI1.1 
 als günstig festgestellt, da eine weitere Steigerung des Wismutgehaltes über diesen Prozentsatz keine nennenswerte Steigerung der Festigkeit mehr ergibt, sondern sich nur ungünstig auf die Dehnung auswirkt. Gegenstand der vorliegenden Erfindung ist demnach eine vergütbare Magnesiumlegierung hoher Festigkeit mit 8-14% Aluminium und 4-14% Wismut, Rest Magnesium. 



   Die wesentlich verbesserten mechanischen Eigenschaften gegenüber der bekannten wismuthaltigen Magnesiumlegierung zeigt ein Vergleichsversuch, der mit Magnesiumlegierungen der folgenden Zusammensetzung durchgeführt wurde :
1. 5% Aluminium, 1% Wismut, Rest Magnesium ;
2. 8% Aluminium, 8% Wismut, Rest Magnesium. 



   Hiebei entspricht Legierung 1 der bekannten Zusammensetzung, während Legierung 2 dem Gegenstand der vorliegenden Erfindung entnommen ist. Die Legierungen wurden   unvergutet   und vergütet untersucht, wobei die Vergütung bei beiden Legierungen in gleicher Weise vorgenommen wurde.

Die Vergütung der erfindungsgemässen Legierungen erfolgt durch Glühen, Abschrecken und Anlassen, wobei das Glühen bei Temperaturen von etwa 360 bis 420  C und das Anlassen bei Temperaturen von etwa 150 bis   2000 C durchgeführt   werden soll. 



   Als empfehlenswert hat es sich bei den erfindungsgemässen Legierungen erwiesen, zwischen dem Abschrecken und Anlassen eine Kaltreckung vorzunehmen.

  Heat-treatable magnesium alloy with aluminum and bismuth content.



   The present invention relates to a thermally tempered magnesium alloy of high strength which can be used with advantage as a material in vehicle and aircraft construction where high strength and the lowest possible weight are important. The alloy according to the invention has contents of aluminum and bismuth.



   An aluminum-containing magnesium alloy with additions of antimony and / or bismuth is already known, but in this alloy the content of the metals antimony or bismuth or both should not exceed a maximum of 2%.



   In contrast to this, the magnesium alloy according to the present invention contains, in addition to 8-14% aluminum, an amount of 4-14% bismuth. The increase in the bismuth content results in a surprising increase in the mechanical properties. As an appropriate lower salary
 EMI1.1
 found to be favorable, since a further increase in the bismuth content above this percentage no longer results in a significant increase in strength, but only has an unfavorable effect on elongation. The subject of the present invention is accordingly a heat-treatable magnesium alloy of high strength with 8-14% aluminum and 4-14% bismuth, the remainder being magnesium.



   The significantly improved mechanical properties compared to the known bismuth-containing magnesium alloy are shown in a comparison test carried out with magnesium alloys of the following composition:
1. 5% aluminum, 1% bismuth, remainder magnesium;
2. 8% aluminum, 8% bismuth, the remainder magnesium.



   Alloy 1 corresponds to the known composition, while alloy 2 is taken from the subject matter of the present invention. The alloys were examined in the unmodified and tempered, the tempering was carried out in the same way for both alloys.

   The tests had the following result:

The alloys according to the invention are tempered by annealing, quenching and tempering, the annealing being carried out at temperatures of about 360 to 420 ° C. and the tempering at temperatures of about 150 to 2000 ° C.



   In the case of the alloys according to the invention, it has proven to be advisable to carry out cold stretching between quenching and tempering.
