Regularities of formation of ternary intermetallic compounds - Part 1. Ternary intermetallic compounds between nontransition elements

The regularities of ternary intermetallic compound formation between nontra nsition metallic elements have been studied by the atomic parameter-pattern recognition method using Villars's system of atomic parameters (R-sp, VE, and X-MB). It has been found that the representative points of ternary comp ound forming alloy systems and that of ternary alloy systems without a tern ary compound are distributed in different regions in the multi-dimensional space spanned by the atomic parameters or their functions, A hyperpolyhedro n model obtained by pattern-recognition methods can be used to describe the boundaries of the zone of ternary compound formation in multi-dimensional space, with good computerized prediction for ternary intermetallic compound formation.
