Stored Energy and its Role in Recrystallization Process

Abstract

The stored energy, present in a material after deformation in the form of dislocation density, plays a crucial role in the recrystallizaton process. It can be evaluated directly using electron diffraction or indirectly using X-ray and neutron diffraction (peak profile study). The stored energy can be also calculated, using deformation models. Knowledge of the stored energy distribution is necessary in quantitative studies of recrystallization. The distribution of stored energy can explain the highly oriented nucleation (case of most of b.c.c. metals) as well as the highly oriented growth (case of most of f.c.c metals).
