In this work, we utilize recent software for precipitation kinetics simulation and couple it
with models for grain growth. Basis of our studies is the thermo-kinetic software MatCalc, which
has been designed for simulation of the evolution of precipitates in general multi-component multiphase
alloy systems. Grain growth approaches of different complexity are incorporated into the
precipitation kinetics framework, investigated with respect to their coupling behavior with
precipitation and precipitate dissolution and, finally, benchmarked on typical grain growth problems
of industrial practice. The example presented in this work comprises austenite grain growth studies
accompanying TiN and NbC precipitation/dissolution during austenitization of a Ti/Nb
microalloyed steel. It is demonstrated that the present approach represents a versatile too
