Abstract

This paper studies the influence to the microstructural evolution of low carbon steel and low carbon Nb steel through experiments in order to improve the microstructure of billet. The results of the study show that electropulsing has significant impact on the phase transformation from austenite to ferrite of low carbon steel and low carbon Nb steel, which improves nucleation rate of ferrite inside austenite grain. And it also shows that electropulsing promotes the nucleation and precipitation of NbCN in low carbon Nb steel and a large number of NbCN particles provide the nucleation sites for austenitic ferritic phase transformation, which improves nucleation rate of ferrite inside austenite grain. The improvement of nucleation rate of ferrite inside austenite grain effectively restrains the formation of pro-eutectoid ferrite omentum at austenitic grain boundaries.
