| Abstract: | The application of electric current pulse(ECP)in metal solidification has increasingly become a new type of technique for microstructure refinement of metals.This paper describes the investigation status of the effect of ECP on refining metal solidification microstructure from four aspects,i.e.,exerting mode of electric current pulse,material selection,choice of the electric current parameters and mechanism discussion.Besides,a new achievement and an expectation had been made of the studies of ECP in metal solidification microstructure. |
