Programma

This course is intended for students at the master level in Materials Engineering and addresses the thermodynamics of materials with focus on the principles that rule the writing of constitutive equations describing the behavior of materials. Aim of this course is introducing the students at the Master level in Materials Engineering to equilibrium and non-equilibrium materials thermodynamics, on the grounds of a rational thermodynamics approach. The part dealing with Equilibrium thermodynamics addresses the issues related to multicomponent real systems. Equilibrium thermodynamics of real pure substances is instead treated in the course ‘Macroscopic thermodynamics’ for students at the bachelor level. Partial molar properties, chemical potential, fugacity and activity are introduced and analysed passing then to techniques of construction of phase diagrams for multicomponent systems. Equilibrium conditions for multiphase multicomponent systems are illustrated also in the presence of external fields. Finally, surface effects on equilibrium thermodynamics are addressed. Thermodynamic transitions are analysed also with reference to special cases like glass transition, which is treated illustrating several approaches. The use of II principle of thermodynamic s is specifically addressed with the aim of constructing constitutive expressions for non equilibrium behavior of elastic, viscous, reacting and relaxing systems. Extensive use is made of thermodynamics with internal state variables.
