为了阐明振动处理提高铸件充型效率的机理，对两相界面的混合和渗透的物理化学行为进行了估计。本研究采用共晶Al/Si合金。研究了凝固过程中初生Si颗粒的结晶行为与合金液流动性的关系。本文的研究结果表明，在铸造过程中施加振动对改善流动性和细化金属组织是有效的。

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.
