| Abstract: | Based on the theory of empirical electron theory(EET) in solid and molecule,according to the strength of a-Cu matrix,the solid solution and precipitation strengthening increments were respectively calculated with the electron number n_A on the strongest bond in alloying phase and electron density difference △ρ on biphase interface.The tensile strength calculation model of copper alloy was proposed.According to the calculation model of CuCrSnZn alloy,the results are consistent with the experimental strength,which indicates the precision and accuracy of the calculation model. |
