将静磁场与交变电场相互作用的电磁振动应用于Al-17%Si过共晶合金的组织细化。定量研究了电磁振动强度和频率与原生硅颗粒细化的关系。在10 Hz到30 kHz的频率范围内，1 kHz附近的振动频率对硅颗粒的细化是最有效的，尺寸高达约5 mm的硅颗粒在该频率下被细化。随着电磁振动强度的增加，精细化程度也随之提高。初生硅颗粒在磁场强度仅约1.6特斯拉(T)的情况下得到了充分的细化。
Electromagnetic vibrations, which are the interaction between a static magnetic field and an alternating electric field, were applied to the structural refinement of Al-17%Si hyper-eutectic alloy. The relationship between the intensity and frequency of the electromagnetic vibrations and the refinement of primary silicon particles is quantitatively investigated. In the frequency range from 10 Hz to 30 kHz, the vibration frequency near 1 kHz was most effective for the refinement of silicon particles, and silicon particles of sizes up to approximately 5 mm were refined at that frequency. The level of refinement increased with increasing the intensity of electromagnetic vibrations. A primary silicon particle was sufficiently refined with a magnetic field intensity of only approximately 1.6 Tesla (T).
