Research Abstract

In order to elucidate the mechanism of the filling efficiency improvement by vibration treatment in a casting process, the physicochemical behavior of mixing and infiltration at the biphasic interface was estimated. Eutectic Al/Si alloys were used for the present study. Relationship between the crystallization behavior of primary Si particles and flowability of the molten alloy under the solidification process was investigated. The results of the present work conclude that applying vibration to a casting process is effective for improving the flowability and refining the metallic structure.
