Abstract

The data obtained as a result of the analysis of crystallogeometric parameters and the structure of state diagrams of binary systems from elements VIIIA and IB periods of the D.I. Mendeleev’s table are presented. It is shown that the classification of the evolution of phase diagrams of binary systems by types, proposed by T.A. Lebedev, correlates with features of concentration dependences of the deviation of atomic volumes in solid solutions from Zen law.

Highlights

Summary

Introduction

The data on phase equilibria and structural-phase states in multicomponent systems is of greatest interest from the perspective of the development of functional materials. Functional materials based on binary alloys from elements VIIIA and IB periods of the D.I. Mendeleev’s table are of keen interest. The search for general laws can be carried out using conventional classifications of binary and ternary state diagrams. State diagrams that exhibit of a weak stability of the crystalline lattice in pretransitional regions prior to phase transitions.
