| Abstract: | A review was made of the research situation of the effect of impulse current treatment on metal solidification structure and metal performance at home and abroad.Based on the principles of electromagnetics and metal solidification,the causes were analyzed of thinning metal grains and improving metal performance by electrical impulse,the major mechanism was shown of electrical impulse affecting metal solidification,and a theoretical prediction was given of the effect law. |
