Recrystallization is a phenomenon where the polycrystalline microstructure of metallic materials
is entirely rebuild after plastic deformation and subsequent thermal treatment. Nowadays, the
kinetics of recrystallization can be well described computationally in many alloy systems. In
turn, physical models describing the influence of recrystallization on precipitation and, in
particular, on coarsening of precipitates located at the recrystallization front and subsequent
release of the pinned recrystallization front, are rare. In the present work, we introduce a new
modelling approach that describes the phenomenon of recrystallization stop by precipitation and
continuation of recrystallization due to precipitate coarsening in the framework of thermo-kinetic
simulation. The computational treatment is verified against experimental data, where good
agreement is achieved.
