    Abstract This paper studies the influence of Ag atomic segregation on the structural evolutions of the mixed (PdAg)309 clusters during the heating processes by using molecular dynamics with a general embedded atom method. The results show that the Ag atomic segregation makes the cluster exhibit a segregate-melting stage in which the energy does not monotonic increase with the increase of temperature. In this stage, the cluster first transforms to form a disorder structure from the initial icosahedron and then a decahedron. By comparing with the cases in the pure Pd309, Ag309, and core-shell (PdAg)309, it is found that More >
