-copper alloy; electrochemical formation; free energy of formation; diffusion coefficient 1 Introduction Alloys of rare earth Ho with other metals (Fe, Co, Ni, Cu, etc) possess electrical, magnetic... chlorides. The free energies of formation for the intermetallic compounds of Ho-Cu systems, the diffusion coefficients and the diffusion activation energy of Ho in the alloy are determined. 2......
650093, China) Abstract: The molecular dynamics method was used to simulate the thermodynamic properties of two binary alloys, Pb8Au2 and Pb9Au1. The formation enthalpy, free energy of formation and excess free energy of two alloys were calculated. The atomic interactions were analyzed in macroscopic and microcosmic view. The values obtained here are consistent well with those of the experiments. Key......
