【Abstract】 In this work the empirical electron theory of solid and molecule is applied to analyze the valence electron structures of solid solutions Cu-Zn and Cu-Ni. The relationship between the parameter η of atom-bond strength and the compositions of alloys is gained by calculation. Comparing to the experimental law between the elastic modulus E and the compositions of alloys, the relationship between η and E that both characterize the atom-bond strength in the crystals has been found. The feasibility to judge the varying rule of properties of alloys from the empirical electron theory is verified in the wider range of solid solubilities.更多还原
