Abstract

In order to describe the physical properties of -Pu from the microscopic scale, we perform molecular dynamics calculation using the analogy material Ag-Au alloy. The melting point, volume heat capacity and linear expansion coefficient of Ag-Au alloys with different doping levels were calculated by the interatomic potentials based on the embedded atomic method (EAM). The results show that the melting points of Ag-Au alloy within all doping levels are around 1400 K, indicating that the doping level has little effect on its melting point. The volume of heat capacity increases with the increasing of the atomic weight of gold, however it is around 2.5 Júcm-3úK-1, and the trend of change is gradually accelerated. The coefficient of linear expansion decreases with the increasing of the atomic weight of gold, and the trend of change gradually slow down.
