Regularities of formation of ternary intermetallic compounds between one transition element and two non-transition elements

The pattern recognition methods and a four-parameter model, Eased on extens ion of Miedema's cellular model of alloy phases, are used to study the regu larities of formation of ternary compounds between one transition element ( T) and two non-transition elements (N, N') (T-N-N' system). The influences of phi (electronegativity), n(ws)(1/3)(valence electron density in Wagner-S eitz cell), R(Pauling's metallic radii) and Z (number of valence electrons in atom) on the formation of the ternary intermetallic compounds were inves tigated.
