Superconducting state parameters (SSP) (viz., electron-phonon coupling strength λ, Coulomb pseudopotential μ* transition temperature TC, isotope effect exponent α and effective interaction strength NOV) of transition metals based binary alloys are studied using - for the first time - a potential formalism with a pseudoatom-alloy model. In the study, noticeable influence of various exchange and correlation functions on λ and μ* has been revealed. The SSP results are found to be in a qualitative agreement with the available experimental data.
