Abstract The alloyed amount of Ce in aluminum of commercial purity has been deter-mined by using radioactive isotope ~(14)Ce and by the method of low tempera-ture electrolysis in organic electrolyte.The distribution of alloying Ce in the Alhas also been detected by means of EPMA,autoradiography and autoradiographySEM.Results showed that the most of Ce in Al is in an alloying state and im-pels the enrichment of Si along grain boundaries.The compounds of CeAl_4 andCe_5Si_3 in the Al as well as the eutectic network structure at grain boundary arefound with the increasing of the amount of Ce contained.The Ce is obviouslyenriched itself along the grain and dendrite boundaries in the as-cast Al withor without annealing.
