Institute of Materials Science and Engineering

The basic knowledge in the field of materials engineering, with emphasis on the relations between the real structure and performance of materials. In-depth knowledge of limit states, in particular the problems of testing mechanical properties and failure mechanisms. The knowledge of the following experimental methods is also assumed: metallography, scanning electron microscopy, X-ray spectral microanalysis (EDS and WDS), Auger spectroscopy.

Graded course-unit credit in the form of presenting an assigned or chosen problem before the group of fellow-students.
Compulsory attendance at exercises. Absence from exercises is dealt with by assigning a topic for a written presentation (usually selected papers from literature).

The course focuses on the explanation of the causes of machine-part failures, failure micromechanisms, methods of macrofractographic and microfractographic studies, classification and description of fracture appearance with the aim of making students familiar with the potentials of applying fractography to the solution of practical production problems, breakdowns and their causes, optimisation of materials selection, etc.
The knowledge of failure micromechanisms and methods of studying them. Understanding the relations between the properties of materials, the causes of their failures, and ways of preventing failures. The application of fractography as an important tool in solving production problems and breakdowns.
