Description
Verfahren zum Vergüten von Aluminiumgußlegierungen durch Glühen, Abschrecken und Altern Es ist bekannt, Aluminiumgußlegierungen durch Glühen, Abschrecken und -Altern zu vergüten. Es gelingt auf diese Weise, die Festigkeit beträchtlich zu steigern. Dagegen sind die erreichten Dehnungswerte so gering, daß die so vergüteten Gußlegierungen für viele Verwendungszwecke unbenutzbar sind. Das vorliegende Verfahren ist bestimmt, diesem Mangel abzuhelfen. Zu diesem Zwecke werden die Gußstücke nach einer mehrtägigen Glühung bei üblichen Temperaturen auf eine um 3o bis i75° tiefere Temperatur gebracht und daraufhin abgeschreckt. Hieran kann ein an sich bekanntes Anlaßverfahren angeschlossen werden.Process for quenching and tempering cast aluminum alloys by annealing, quenching and aging It is known to produce cast aluminum alloys by annealing, quenching and -Age to reimburse. In this way it is possible to increase the strength considerably increase. On the other hand, the elongation values achieved are so low that they are tempered in this way Cast alloys are unusable for many purposes. The present proceedings is intended to remedy this deficiency. For this purpose, the castings are made according to annealing for several days at normal temperatures to a temperature of 30 to 175 ° lower Temperature brought and then quenched. A known per se can be added to this Tempering procedures are connected.
Wohl ist es bekannt, Aluminiumknetlegierungen von einer niedriger als der Glühpunkt liegenden Temperatur abzuschrecken. Doch geschieht das ausschließlich zu dem Zwecke, um die Härte zu steigern, während es sich bei der Anwendung des vorliegenden Verfahrens- auf Aluminiumgußlegierungen jeder Art um die Verbesserung der Dehnung handelt. Ausführungsbeispiel Eine Legierung nach Art des Gußlautals (q. °/o Cu, 2 °/o Si, Rest Al) wird in Kokillen gegossen; die gegossenen Formstücke werden mehrere Tage bei 500° C geglüht; sie werden dann auf q.7o bis q.50° gebracht und abgeschreckt. Die erreichten Dehnungswerte betragen io bis 12 °/o bei einer Festigkeit von 2o bis 25 kgjmm2.It is well known to wrought aluminum alloys from a lower than the temperature lying at the glow point to quench. But that happens exclusively for the purpose of increasing the hardness while applying the present Process on aluminum casting alloys of all types to improve elongation acts. Embodiment An alloy like the Gußlautals (q. ° / o Cu, 2% Si, remainder Al) is poured into permanent molds; the cast fittings become several Annealed for days at 500 ° C; they are then brought to q.7o to q.50 ° and quenched. The elongation values achieved are 10 to 12% with a strength of 20 up to 25 kgmm2.
