“…In reality, although the interfacial energy depends on the crystal orientation relationship between the ferrite phase and the austenite phase, the interfacial energy is assumed to be constant for all interfaces. It should be noted that the geometry coefficient of the nucleation site on the grain boundary is found in the published works of Thiessen et al 25) and Offerman et al 26) The coefficient of the deformation band, ψ d , is assumed to be the same as that of the grain boundary face, ψ g .…”

A simulation model to describe the austenite-to-ferrite transformation in the deformed austenite phase is developed using the crystal plasticity finite element and multi-phase-field methods. Using the developed model, we simulate the plastic deformation behavior of the polycrystalline austenite phase during plane strain compression and the subsequent isothermal austenite-to-ferrite transformation. The ferrite nucleation behaviors on the elongated austenite grain boundary and the deformation bands formed in the austenite grain are estimated on the basis of the classical nucleation theory. In this study, the effects of plastic deformation of the austenite phase and the holding temperature on the transformation kinetics and the ferrite grain size are investigated. The simulation results show that transformation is accelerated with an increase in the strain in the austenite phase. Furthermore, it is confirmed that ferrite grain refinement occurs by the enhancement of ferrite nucleation within the deformed austenite grain interior and by the suppression of ferrite grain growth due to hard impingement.KEY WORDS: austenite-to-ferrite transformation; multi-phase-field method; crystal plasticity finite element method; microstructure.

“…Thiessen et al [66] introduced the CNT into a general PF code and carried out the simulation of ferrite formation from a fully and a partially austenitic matrix in a dual-phase steel. The comparison between the simulations and the in-situ synchrotron experiments showed that using the temperature-and compositiondependent nucleation rates significantly improved the agreement between experimental and simulated transformation kinetics.…”

The mesoscopic modeling developed rapidly in the past three decades is a promising tool for predicting and understanding the microstructure evolution at grain scale. In this paper, the recent development of mesoscopic modeling and its application to microstructure evolution in steels is reviewed. Firstly, some representative computational models are briefly introduced, e.g., the phase field model, the cellular automaton model and the Monte Carlo model. Then, the emphasis is put on the application of mesoscopic modeling of the complex features of microstructure evolution, including solidification, solid-state phase transformation, recrystallization and grain growth. Finally, some issues in the present mesoscopic modeling and its perspective are discussed. microstructure evolution, steel, phase field, cellular automaton, Monte Carlo Citation:Xiao N M, Chen Y, Li D Z, et al.
