Obiettivi formativi

The course aims at providing students with knowledge about thermodynamics and kinetics of materials.

Contenuti

Thermodynamics and kinetics of solids.
Phase transformation processes and the kinetic mechanisms (diffusion, transport) that are at their base.
Fundamentals of some spectroscopic techniques able to investigate the correlations between structure, dynamics and functional properties of some classes of solids.

Programma esteso

Thermodynamics and kinetics of phase transformations.
Fundamentals of Landau’s theory. Order-disorder transitions.
Solid solutions. Polycrystalline systems and
formation of grain boundary. Homogeneous and heterogeneous
nucleation during solidification and solid-solid transformation.
Kinetics in solid state. Processes of heat and matter transport.
Continuity equations. Principles of thermodynamics of irreversible
processes. Onsager relations. Diffusion: Fick’s law. Diffusion
equation and solutions. Applications to diffusion processes in
solids. Structural aspects of solid state transformation.
Diffraction techniques: short and long order, Scherrer equation,
radial distribution function, types of disorder. Structure of glasses
and mechanisms of ion transport. X-rays spectroscopy: EXAFS, XANES.
Diffusion coefficients measured by NMR.
