Abstract

This study investigated the microstructure properties of A356 and AC8A alloys with a rheocasting mold using an inclined cooling plate. In addition, a formability evaluation was performed according to the solid fraction. Regardless of the position, the overall microstructure was shown to be uniform and a finer crystal structure was obtained as the solid fraction increased. The study confirmed that the molding pattern changed according to the solid fraction and that the spherical α-Al and eutectic α were identified. The results of the formability according to the solid fraction of A356 and AC8A alloys were similar to the simulation results.
