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.

为了阐明振动处理提高铸造充型效率的机理，对两相界面的混合和渗透的物理化学行为进行了评价。本研究中使用了Eu 3 + Al/Si合金。研究了凝固过程中初晶Si颗粒的结晶行为与合金熔体流动性的关系。本工作的结果表明，施加振动铸造过程是有效的，以改善流动性和细化金属组织。
