Crystal plasticity model of induction heating-assisted incremental sheet forming with recrystallisation simulation in cellular automata

Abstract To relate the thermomechanical behaviour and microstructural evolution of heat-assisted incremental sheet forming (SPIF) for Ti–6Al–4 V sheet, multi-scale models based on crystal plasticity finite element model (CPFEM), representative elementary volume (RVE), cellular automaton (CA) were established in this article. An experimental-scale CPFEM was built advance to provide macrograin level strain, strain rate, temperature output data, which then used RVE CA as inputs simulate throughout SPIF process. The results include pole figures, dynamic recrystallisation (DRX) maps, statistics alpha (?) phase (?-Ti) alloy from stage 700 $$^\circ{\rm C}$$ ?
