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......
was investigated. The molar Gibbs free energy function of mechanically activated samples was calculated from the structural defects such as amorphization, dislocation and surface energy. According to the molar Gibbs free energy function, the equilibrium temperature of mechanical reduction of silver oxide milled for 21 h was estimated at about 304 K. Consequently, at this temperature silver oxide......
