Global recrystallisation model of low carbon sheet steels with different cementite contents

This paper discusses the influence of Particle Stimulated Nucleation (PSN) on the overall process of nucleation and subsequent grain growth in low carbon (LC) steels and proposes a global recrystallisation kinetics model based on fundamental physical metallurgy principles. The model takes into account the cementite content, which depends on the nominal carbon content, and the second phase particle size. The deformation field around cementite particles and its influence on processes is analysed. Finally, experimental evidence is given to show the accuracy of the theoretical predictions.
