Abstract:The microstructure and composition in hot dip aluminized layer of steel were investigated through scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffractometry (XRD) and energy dispersive spectroscopy (EDS). The amorphous phase is found in the outer layer of hot-dip aluminized layer. In order to clear the phenomenon, the Al-Fe alloy liquids used in hot dip aluminizing were quickly solidified and slowly solidified respectively. The results show that under quick solidification both Al-Fe alloy samples with or without La contain amorphous phase. While the Al-Fe alloy liquids are solidified slowly, the amorphous phase is only found in sample with La.
Key words: hot-dip aluminizing; Al-Fe alloy liquid; rare earths; amorphous phase
