Effect of electropulsing on austenite to ferrite transformation in low-carbon steel

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.

Automated summary

Electropulsing can promote the phase transformation from austenite to ferrite in low-carbon steel, facilitating the precipitation of ferrite within austenite grains and providing a means to control the transformation process.
