Verfahren zur Herstellung einer Nietverbindung mit einem Niet aus einer ODS-Superlegierung

摘要

The invention relates to a method of producing a riveted joint using a riveting tool. The essence is that a pin-type precursor material made of a recrystallised, coarse-grained ODS superalloy having an iron or nickel base and having a grain elongation in the longitudinal direction of 5:1 to 50:1 is used for the rivets. The rivet heads are produced at specified process temperatures with a pin temperature of between 600 and 1000 DEG C and a tool temperature of between 50 and 300 DEG C.
