We explore the application of electropulsing for the control of phase transformation in a low-carbon steel.The effect of electropulsing on the transformation from austenite to ferrite in continuous casting low-carbon steel slab has been studied through experimental and thermodynamic investigations.The results reveal that electropulsing promotes the precipitation of ferrite within austenite grain in the low-carbon steel.When the electropulsing intensity increases,the precipitation of ferrite increases within austenite grains,and ferrite omentum precipitates become thinner along the austenite grain boundary.The results provide a basis for controlling the austenite to ferrite transformation in low-carbon steel.
