Abstract

A method for manufacturing a metallic material for rheocasting or thixoforming and a metallic material formed using the method are provided. The method includes: applying an electromagnetic field to a vessel and loading a molten metal into the vessel; and cooling the molten metal to form a metallic material for rheocasting or thixoforming. The entire volume of molten metal is rapidly and uniformly cooled throughout, from the wall toward the center of the vessel, without generating latent heat caused by the formation of solidification layers at the early stage of cooling. The molten metal in the vessel is cooled rapidly below its liquidus temperature within 1-10 seconds after the loading of the molten metal into the vessel, so that numerous uniform crystal nuclei are created throughout the entire volume of molten metal to form a metallic material having uniform, micro, spherical particles.
