Abstract :

General formulation of thermodynamics of metastable states and relaxation is proposed and discussed. Semiclassical Models
are used also as a tool for solving problems in Materials Science. Wide range of processes and materials are considered.
Among them crystals, containing micro and macro defects, like point defects, vacancies, dislocations, pores and cracks. Influence
of these defects on properties of materials, including strength and fracture ones, are discussed. Polar materials, containing pores
and inclusions of different phases are investigated. Cavitation phenomenon in polar materials in external fields is predicted.
Semiclassical theory of the basic properties of nanoobjects is formulated. Friction of collective electrons in nanoobjects is taken
into account. Comparison of experimental data with theoretical ones shows rather a good agreement. These data can be useful for
Master Degree and PhD students, studying Materials Science.
