The influence of Ce or Ce and Mn combined additions on the morphology ofα-Fe phases in recycled Al-Si alloys was experimentally investigated by microstructure observation and room temperature tensile testing.It is found that Ce modifes the morphology of α-Fe phase from the large Chinese script-like into the individual and fne nodular shape.A combined addition of Ce and Mn results in the promotion of primary α-Fe formation,and their size increases considerably with the increase in Ce content.The mechanism of the above morphological changes was discussed in accordance with the nucleation and growth of α-Fe phase during solidifcation.
