摘要: In this study a new method is introduced to produce bimodal grain structures in low carbon steels. This based on cold rolling of dual-phase and appropriate annealing treatments. The difference the recrystallization behaviour ferrite martensite yields heterogeneous microstructure with distribution coarse fine grains. These types microstructures are interest for optimizing balance strength uniform elongation ultrafine-grained
