Influence of Niobium on the Dynamic Recrystallization of Nickel
ABSTRACT
This report results from a contract tasking Ecole des Mines de Saint-Etienne (ENSM-SE) as follows: The project will
study the influence of niobium in solid solution, without intermetallic precipitates, on dynamic recrystallization of high purity
nickel. Nb plays an important role, although not well understood, on the hot deformation mechanisms of superalloys like
Inconel 718. Alloys of 0, 0.1, and 1 weight percent niobium will be prepared and studied to determine their dynamic and
post-dynamic recrystallization mechanisms and kinetics.
