文摘

A thorough study of surface segregation energies of 41 elements in Al is performed. Segregation energies vary periodically with the atomic numbers of impurities. 41 elements are classified into 3 groups according to the signs of segregation energies. The results are validated by the surface/total concentration ratio in Al alloys.
