Study of dislocation-twin boundary interaction mechanisms in plastic deformation of TWIP steel by discrete dislocation dynamics and dislocation density-based modeling

•A DDD model involving dislocation-TB interactions for TWIP steel with low SFE was established.•The complex dislocation reactions for the 60° dislocation at the TB were determined based on the energy criterion.•An improved DDB model was established by considering the dislocation type in describing t...
