Buken, H., & Kozeschnik, E. (2017). A model for static recrystallization with simultaneous precipitation and solute drag. Metallurgical and Materials Transactions A. https://doi.org/10.1007/s11661-016-3524-5
In the present work, we introduce a state parameter-based microstructure evolution model, which incorporates the effect of solute atoms and precipitates on recrystallization kinetics. The model accounts for local precipitate coarsening at grain boundaries, which promotes an average grain boundary movement even if the Zener pinning force exceeds the driving force for recrystallization. The impact of solute drag on the grain boundary mobility as well as simultaneous precipitation is discussed in detail. The model is validated on experimental data on recrystallization in V-micro-alloyed steel, where excellent agreement is achieved.
