Abstract

The recrystallization kinetics of nanostructured copper samples processed by dynamic plastic deformation was investigated by electron backscatter diffraction. It was found that the evolution of the recrystallized volume fraction as a function of annealing time has a very low slope (n=0.37) when plotted as an Avrami plot. Various reasons for such a low slope are discussed, including possible recrystallization during storage of samples, and the heterogeneous recrystallization kinetics. The effects of heterogeneous recrystallization kinetics are illustrated by a simplified model with a fast and a slowly recrystallizing region.
