Simulation of Austenite Grain Growth in Low-Alloyed Steels upon Austenitization

A model has been developed that describes the grain growth upon austenitization, taking into account the pinning of moving grain boundaries by carbonitride precipitates. The behavior of these precipitates is described using our previously developed approach for predicting the evolution of carbonitride particles. The software implementation of the model was carried out, and numerical calculations were performed. The calculation results have been compared with the experimental data in the literature and their good agreement is shown.
