Credits allocated: 5
 
Recommended semester/trimester: Materials Engineering - master (compulsory), 1. semester
Materials Engineering - master (compulsory), 1. semester
Level of study: 1. + 2., 2.
Prerequisites for registration: none
 
Assesment methods:
The student is classified in three sequential steps:
1. Two written proof of knowledge on exercises, totally maximum 20 points.
2. Exam – wtitten test, maximum 50 points.
3. Exam – interview, maximum 30 points.
The final result expressed by mark is given with the sum of points obtained in particular steps: 92 - 100 (A), 83 – 91 (B), 74 – 82 (C), 65 – 73 (D), 56 – 64 (E), less than 56 (FX).
 
Learning outcomes of the course unit:
The student gained knowledge of the solid state structure over the extent mastered at the study of subjects “Materials Science” and “Physics”. He/she became familiar with the classification and properties of lattice defects inclusive of interactions between them. He/she knows diffusion-related topics (Fick's laws, Kirkendall effect, diffusion coefficient, thermodynamic factor, up-hill diffusion) including mechanisms of diffusion and solving kinetic equations. He/she gained knowledge of both phenomenology of adsorption and segregation processes and formalism of equilibrium and non-equilibrium segregation at internal surfaces of the solid state. He/she became familiar with fundamental mechanisms of strengthening (solution strengthening, precipitation strengthening, grain boundary strengthening) and the role of lattice defects in strengthening of materials.
 
Course contents:
Structure of solid state (amorphous, crystaline and quasicrystalline materials; chemical and physical bonds)
Lattice defects (thermal vibrations, point, line, surface and volume defects)
