The Hamiltonian of the electron‐phonon interaction is derived and applied to the description of disordered transition metal alloys. The coupled set of equations for the electron and phonon Green functions is derived with the help of the equation‐of‐motion technique. Neglecting the vertex corrections in the self‐energy operators the closed self‐consistent system of equations is obtained. The relevant configurational averaging is performed in the framework of the CPA. The electronic specific heat in the low‐temperature limit is calculated.
