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

The regularities of ternary intermetallic compound formation between nontransition 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 com...

Description
Summary:The regularities of ternary intermetallic compound formation between nontransition 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 compound forming alloy systems and that of ternary alloy systems without a ternary compound are distributed in different regions in the multi-dimensional space spanned by the atomic parameters or their functions. A hyperpolyhedron 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.
