Introduction Pulsed electric current technology refers to a method that applies electric field during the solidification process of molten metal to control the solidification microstructure and property of material.
Viewing from the existing literatures [1]-[4], with the join of the pulsed electric current, it can significantly refine the grain structure and improve the macroscopic property of materials.
