Abstract

To develop a multiscale hot-working model that enables us to simulate macroscopic mechanical behaviors depending on microstructural evolution by the coupling the finite element (FE) method and phase-field (PF) method, the multi-phase-field-dynamic recrystallization (MPF-DRX) model has been applied to transient deformation simulation, where strain rate and temperature rapidly change during deformation. As a result, it has been confirmed that the variations in the macroscopic stress-strain curve and average grain size during deformation are in good agreement with the experimental observation qualitatively.
