Verfahren zur Herstellung ringförmiger geschmiedeter Verbundkörper
Es wurde bereits vorgeschlagen, Verbundkörper aus verschiedenartigen Stählen zu schmieden oder zu walzen. Ferner ist bekannt, von Verbundgusskörpern Scheiben abzutrennen und dieselben z. B. durch Schmieden weiterzuverarbeiten.
Befriedigende Ergebnisse konnten aber mit diesen Verfahren nicht erreicht werden, da ein nur von aussen wirkender Walz-oder Schmiededruck wegen der verschieden starken Verformung ein Aufreissen vorwiegend in der Übergangszone der beiden, den Verbundkörper bildenden Stähle verursachte.
Um ringförmige Verbundkörper einwandfrei herzustellen, werden die vom Verbundgusskörper abgetrennten Scheiben oder Ringe erfindunggemäss über einen Dorn geschmiedet. Durch diese Massnahme erhalten die Körper von innen Halt und ein Aufreissen wird wegen der nun mit genügender Gleichmässigkeit erfolgenden Verformung beider Werkstoffe mit Sicherheit vermieden.
Aus solchen geschmiedeten Verbundkörpern können mit Vorteil z. B. Fräser, Zahnräder und

Process for the production of annular forged composite bodies
It has already been proposed to forge or roll composite bodies from different types of steel. It is also known to separate discs from composite cast bodies and use the same z. B. further processed by forging.
However, it was not possible to achieve satisfactory results with this method, since a rolling or forging pressure acting only from the outside caused tearing mainly in the transition zone of the two steels forming the composite body due to the different degrees of deformation.
In order to produce ring-shaped composite bodies properly, the disks or rings separated from the composite cast body are forged over a mandrel according to the invention. This measure gives the bodies support from the inside and tearing open is definitely avoided because the two materials are now deformed with sufficient uniformity.
For such forged composite bodies, for. B. cutters, gears and
