Modeling the Dynamically Recrystallized Grain Size Evolution of a Superalloy

Abstract:

The evolution of the UNS 6617 alloy microstructure during the hot deformation and the effect of hot deformation parameters on the grain structure and on the dynamic recrystallization were studied. A mathematical model which is capable to calculate the dynamically recrystallized austenite grain size of the alloy was built.
