The research status of pulsed electric field on effects of pure aluminum solidification from the internal and external factors of electric current was expounded.The internal aspect included the selection of electric current pulse type and pulse parameters

and the external aspect included the exerting way and power-on time of pulsed electric field.Then the reaction mechanism of pulsed electric field on pure aluminum solidification process was described through nucleation acceleration aspect

such as magnetic force pulse

cluster structure theory

undercooling and nucleation barrier

and grain growth inhibition aspect

such as Joule heating effect

Peltier heating effect and dendrite fracture.At last

a conclusive decision was not put forward in mechanism

and problems still exist in industrial production

however

the technology can present the future green solidification technique with further exploration.
