Modeling of discontinuous dynamic recrystallization of a near-α titanium alloy IMI834 during isothermal hot compression by combining a cellular automaton model with a crystal plasticity finite element method.

Highlights: [•] DDRX of IMI834 alloy is modeled by combining a CA method with CPFEM. [•] Non-uniform deformation at the grain level is considered in the model. [•] The predicted recrystallization kinetics displays nonlinear behavior. [•] The nucleation mode appears heterogeneous and non-random. [•] Average re-grain size increases with temperature or decreasing strain rate. [ABSTRACT FROM AUTHOR]
