The phase stability of the Ni-based compounds Ni3Al, Ni3Si, Ni3Ga and Ni3Ge was studied by calculating the total electronic energy in the L12 and D022 phases on the basis of the recursion method within the tight-binding approximation. A close relationship was observed between the total electronic energy difference of the L12 and D022 phases and the number of valence electrons in the Ni-based compounds as well as in Al-based ones, Al3X (X = Ti, Y, Zr and Nb). For the Ni-based compounds, a structural change from L12 to D022 by alloying, in which Ni atoms are replaced by substitutional solute elements, is predicted.
