| Abstract: | The coalescence of two iron clusters (Fe300+Fe300 → Fe600) at temperatures below the cluster melting points has been studied by molecular dynamics (MD). At temperatures ≈200°C below the melting point phase change from the icosahedral Fe300 structure to the face centered cubic (fcc) Fe600 structure occurs even though the clusters are not molten. Moreover, surface melting is not required for the coalescence or the phase change. At lower temperatures elongated Fe600 clusters that are not fcc, and that may be metastable, are formed. | |
