Secondary phase and inclusions in 3104 aluminum alloy big flat ingot were observed by SEM(scanning electron microscope) and EDS(energy dispersive spectrometry).The results show that there exists a lot of coarse skeleton(FeMn)Al6 phase and a little α-Al(MnFe)Si
Mg2Si and free Si-rich phase in the 3104 aluminum alloy flat ingot.Inclusions in the flat ingot are mainly composed of oxides
residual fluxes and Si-rich or Ti-rich intermetallic compounds.The origination of inclusion in the flat ingot was approached
and countermeasures of eliminating or reducing coarse compound and inclusions were presented.
