Effects of Plate Magnetic Field on Iron-rich Phase of Al-20Si-10Fe Alloy during Solidification

摘要：

　　This paper studies iron-rich phase transformation law and mechanism of Al-20Si-10Fe alloy under the effect of plate magnetic field.with optical microscopy(OM),scanning electron microscopy(SEM),energy dispersive spectrum(EDS)and transmission electron microscopy(TEM).The results show that plate magnetic field is directly involved in the phase transformation of iron-rich phase,making iron-rich phase change from lath-shaped β-Al5FeSi to herringbone-shapedα-Al8SiFe2.The enforcement of plate magnetic field during the phase-transforming process of β-Al5FeSi→α-Al8Si Fe2 makes block α-Al1.3Si7.8Fe2.1 phase yield out.(nd) precipitation of α-Al1.3Si7.8Fe2.1 phase is affected by the transforming process ofβ-Al5SiFe phase→α-Al8Si Fe2phase.
