Learning outcomes: Know - modern theories about the structure of metals and alloys; - principles of diffraction of X-rays; - types of defects in crystals; - thermodynamics of phase formation and solid solutions. Be able to: - carry out phase and structural analysis of alloys; - refine the crystal structure of the material; - determine the model of the crystal structure of the material. - determine the type and concentration of defects in the material. Have - knowledge in Rietveld method - knowledge in methods of phase analysis - skills to work with specialized software and databases.
Required prior and related subjects: Prerequisites: 1. Chemistry; 2. Physics; 3. Crystallography; 4. Modern materials science. Co-requisites: 1. Physical properties and methods of materials characterization.
