Abstract

and alloys both prepared from aqueous solutions has been made to see whether they have nonequilibrium structures. Their structural models were constructed and examined by the correlation method. The model for the Co-W alloy consists of close packed tetrahedra, each composed of four hard spheres of equal size. The tetrahedron contains three Co atoms and one W atom of 2.55A in diameter.In modeling the Ni-P alloys, however, Ni and P atoms were treated as non-hard spheres of different mean diameters; 2.61A and
