Description
Die Erfindung betrifft ein Verfahren zum Verfestigen von Oberflächen an einem Bauteil aus vergütetem Stahl durch Hochtemperatur-Festwalzen.The The invention relates to a method for solidifying surfaces a component made of tempered Steel by high temperature deep rolling.
Es
sind zahlreiche Bauteile bekannt, die bei ihrer Anwendung schwingend
beansprucht werden. Um zu vermeiden, daß derartige Bauteile häufig schon
bei relativ kleinen Schwingbeanspruchungen versagen, kann der Bauteilentwurf überdimensioniert oder
ein festeres, daher aber auch teureres Material verwendet werden.
Alternativ ist es bekannt, einen Ausgleich zwischen Gewichtsreduzierung
und Kosten dadurch herbeizuführen,
daß zumindest
die höchstbelasteten
Oberflächen
der Bauteile einer mechanischen Behandlung unterzogen werden, insbesondere
durch Festwalzen. Das gilt z. B. für den Bereich der Automobilindustrie
(z. B.
Der Erfindung liegt daher das technische Problem zugrunde, das Verfahren der eingangs bezeichneten Gattung dahingehend weiter zu entwickeln, daß die durch seine Anwendung erzielbaren Schwingfestigkeiten größer als die Schwingfestigkeiten sind, die mit bekannten Verfahren erhalten werden.Of the The invention is therefore based on the technical problem, the method to further develop the genus described in the introduction, that the by its application achievable vibration strengths greater than the vibration strengths are obtained by known methods become.
Zur Lösung dieser Aufgabe ist das Verfahren der eingangs bezeichneten Gattung dadurch gekennzeichnet, daß zumindest ein festzuwalzender Bereich des Bauteils vor dem Festwalzen auf eine im Bereich der dynamischen Reckalterung liegende Temperatur erwärmt, während des Festwalzens in diesem Temperaturbereich gehalten und nach dem Festwalzen abkühlen gelassen wird.to solution this task is the method of the type described characterized in that at least a festzuwalzender area of the component prior to deep rolling on a temperature in the range of the dynamic strain age aging heated while held the deep rolling in this temperature range and after the deep rolling cooling down is left.
Es wurde festgestellt, daß eine thermisch-mechanische Behandlung durch Festwalzen im Temperaturbereich der dynamischen Reckalterung im Vergleich zu den bisherigen, bei Raumtemperaturen vorgenommenen Festwalzverfahren zu signifikant größeren Schwingfestigkeiten führt. Die Ursache für diese besonders ausgeprägten Verbesserungen sind während der schwingenden Belastung besonders stabile Druckeigenspannungen aufgrund der dynamischen Reckalterung. Das hat zur Folge, daß Herstellungskosten und/oder Gewicht eingespart werden können.It it was found that a Thermal-mechanical treatment by deep-rolling in the temperature range the dynamic strain aging compared to the previous, at Room tempering deep-rolling method too significant greater vibration resistance leads. The cause of these most pronounced Improvements are during the swinging load particularly stable residual compressive stresses due to the dynamic strain aging. This has the consequence that production costs and / or weight can be saved.
Weitere vorteilhafte Merkmale der Erfindung ergeben sich aus den Unteransprüchen.Further advantageous features of the invention will become apparent from the dependent claims.
