Theoretical analysis of binary (solid liquid)‎ phase diagrams for two metals

Abstract EN

Thermal equilibrium diagrams (phase diagrams) give informations on the phases present and their compositions at equilibrium in alloy systems.

A knowledge of thermodynamic stability of molecular structure has an important effect for understanding phase transformations in materials which are represented in phase diagrams.

Theoretical method of calculating phase diagrams by using thermodynamic properties is using in this work.

Phase diagrams of two metals completely soluble in liquid and solid state with assuming that diagrams without miscibility gap are considered as diagrams of ideal solution while with miscibility gap are considered as diagrams of regular solutions.

By comparing the results obtained from the theoretical method by computer program with the experimental method by using the thermal analysis which are considered as stander diagrams in all references.

The maximum difference between theoretical and experimental diagrams is 40 %.

The minimum difference between them is 0.086 %.
