Abstract
The invention relates to a process for producing a riveted joint using a riveting tool. The essential feature is that a pin-shaped blank of a recrystallized, coarse-grained iron-based or nickel-based ODS superalloy having a grain elongation in the longitudinal direction of 5:1 to 50:1 is used for the rivets. The production of the rivet heads is performed under defined process temperatures, at a pin temperature between 600.degree. and 1000.degree. C. and at a tool temperature between 50.degree. and 300.degree. C.
