A novel technique for developing bimodal grain size distributions in low carbon steels Poole, W. J. (Warren J.); Militzer, Matthias; Azizi-Alizamini, Hamid

Abstract

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