The textbook outlines issues related to the thermodynamic description of one-, two- and three-component metal systems in the liquid state. The main methods for experimental research of the thermodynamic properties of liquid alloys are outlined. The structure and thermodynamic properties of individual liquid metals are considered. The relationship between the phase diagram and the thermodynamic properties in the liquid state of binary metal systems is discussed. Particular attention is paid to systems with the formation of intermetallic compounds, their structure and properties in the liquid phase. Methods for the analytical representation of the concentration dependence of thermodynamic functions in binary liquid metal systems are considered. The most common methods for calculating the thermodynamic properties of liquid ternary metal systems based on data on boundary binary systems are described.

The textbook is intended for students of higher educational institutions studying in the master's program "Materials Science of Nanomaterials and Electronic Components" in the direction of master's training "Technical Physics". It can also be used when teaching students in the areas of training "Materials Science and Technology of Materials", "Metallurgy", in advanced training systems, in institutions of additional professional education.
