KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bekanntlich hat Aluminium die Eigenschaft, j fast bis zu 5 pCt. Silber aufzunehmen, ohne dafs eine Mengenvermehrung eintritt, woraus hervorgeht, dafs ein derartiger Zusatz von Silber zum Aluminium eine Verdichtung des Aluminiums herbeiführt. Hiermit ist gleichzeitig die Wirkung verbunden, dafs das Aluminium wesentlich fester und härter wird.As is well known, aluminum has the property that j is almost up to 5 pCt. To pick up silver without that there is an increase in quantity, from which it follows that such an addition of Silver to aluminum brings about a compression of the aluminum. This is at the same time connected with the effect that the aluminum becomes much stronger and harder.
Der Silberzusatz hat jedoch, sobald derselbe etwa 2 pCt. übersteigt, wiederum die nachtheilige Wirkung, dafs das Aluminium mit der zunehmenden Dichte auch spröder wird, so dafs eine solche Aluminium-Silber-Legirung bei Verarbeitung durch Schmieden, Walzen oder Ziehen sehr häufig geglüht werden mufs.The silver addition has, however, as soon as it is about 2 pCt. exceeds, in turn, the disadvantageous effect that the aluminum becomes more brittle with increasing density, so that such an aluminum-silver alloy is processed by forging or rolling or drawing must be annealed very frequently.
Die vorliegende Erfindung betrifft nun ein Verfahren, welches es ermöglicht, dem Aluminium eine thunlichst weitgehende Verdichtung zu Theil werden zu lassen, und welches dabei doch einen für die vorerwähnte Bearbeitung geeigneten Zähigkeitsgrad der Masse sichert.The present invention now relates to a method which enables the aluminum to allow as far as possible a compression to be part of it, and what that means but ensures a degree of toughness of the mass suitable for the aforementioned machining.
Das Verfahren ist gekennzeichnet durch einen je nach dem Verwendungszweck der Masse von 0,1 bis 1 pCt. steigenden Zusatz von Magnesium zu dem durch Silber verdichteten Aluminium.The method is characterized by a depending on the intended use of the Mass from 0.1 to 1 pCt. increasing addition of magnesium to that condensed by silver Aluminum.
Das Verfahren wird in folgender Weise ausgeführt :The procedure is carried out in the following way:
Nachdem das aus Aluminium und Silber bereitete Bad so lange und so stark erhitzt worden ist, bis Silber und Aluminium eine vollkommene Legirung eingegangen sind, wird das Bad auf 500 bis 6oo° C. abgekühlt und nunmehr der geeignete Magnesiumzusatz in das Bad eingeführt. Damit das Magnesium hierbei nicht verbrennt, geschieht die Einführung zweckmäfsig in der Weise, dafs das Magnesium in ein dünnes Aluminiumblech fest eingehüllt und dieses Packet in das Bad untergetaucht wird.After the bath made of aluminum and silver has been heated for so long and so much is until silver and aluminum have formed a perfect alloy, the bath is cooled to 500 to 600 ° C. and now the appropriate magnesium additive has been introduced into the bath. So that the magnesium does not burn in the process, the introduction is expediently done in such a way that this Magnesium wrapped tightly in a thin sheet of aluminum and submerged this packet in the bath will.
Wie bekannt, übt auch ein Zusatz von Magnesium auf Aluminium eine verdichtende Wirkung aus. Es kann daher bei dem vorliegenden Verfahren der Silberzusatz geringer genommen werden als er sonst zur Herbeiführung einer bestimmten Dichtigkeit erforderlich wäre.As is known, the addition of magnesium to aluminum also has a densifying effect the end. The silver addition can therefore be reduced in the present process than would otherwise be necessary to achieve a certain tightness.
Von besonderer Bedeutung aber ist es, dafs durch den Magnesiumzusatz· der Aluminium-Silber-Legirung ein erheblicher Grad von Zähigkeit ertheilt wird, so dafs das nach dem vorliegenden Verfahren behandelte Aluminium Eigenschaften besitzt, welche dasselbe gleichmäfsig gut für eine Bearbeitung durch Schmieden, Walzen und Ziehen, sowie auch für Drehen, Feilen, Poliren und dergl. geeignet machen.But it is of particular importance that the addition of magnesium to the aluminum-silver alloy a considerable degree of toughness is imparted, so that according to the present Process treated aluminum possesses properties which are the same evenly well suited for processing by forging, rolling and drawing, as well as turning, filing, polishing and the like do.
