Full-time form

Know the laws of thermodynamics, the method of thermodynamic potentials, general conditions of thermodynamic equilibrium, equilibrium conditions in homogeneous and heterogeneous systems, partial and integral thermodynamic functions, thermodynamic functions of ideal and real solutions, quasi-chemical theory of solutions. Be able to apply in practice the method of Gibbs thermodynamic potentials, analyze the main types of state diagrams of two-component systems using isobaric-isothermal potential, calculate equilibrium curves and build state diagrams. Have basic skills to graphically determine partial and relative partial thermodynamic functions by known integrals for binary systems, calculate partial and relative partial functions for one of the components by known partial functions of the second component.

The course "Phase formation processes in amorphous and nanocrystalline systems" considers both classical and modern achievements in the field of the theory of crystallization and amorphization of metal systems; theory of nucleation of binary and multicomponent systems. The purpose of studying the discipline is to master the basic laws of the theory of homogeneous and heterogeneous nucleation in application to amorphous metal systems. The educational task of the course is to master the methods of calculation and experimental measurements of the main parameters of the crystallization process for specific amorphous systems. The task is to acquaint students with the laws of homogeneous and heterogeneous crystallization for single-component and multicomponent systems, as well as processes of amorphization of metal systems, training in methods of calculating the main characteristics of the crystallization process for specific binary systems.
