Ing. Lenka Klakurková, Ph.D.

Institute of Materials Science and Engineering

Mastering the methodology of assessment of the real problems of practice relating to the material and the quality and technology of its processing.

General knowledge and basic knowledge of mathematics, physics and chemistry from secondary school. Knowledge of material science corresponding to the level of subjects BUM, 3SV, etc.

The subject is led by an iterative form of discussion on specific issues and completing the necessary theoretical knowledge necessary for its successful solution.
In case of interest, the preparation of metallographic specimens and microscopic observation, or other additional analytical methods necessary for solving the given problems, are carried out.

Evaluation based on active approach during lectures.

Getting acquainted with the methodology of evaluating real production problems.
Acquiring basic methods of preparation, observation and evaluation of macro and micro structure of metallic and non-metallic materials using modern methods of light and electron microscopy.
Implementation of theoretical knowledge from the field of material sciences into real analysis of causes of damage.
Assessment of real manufacturing problems related to component damage after operational stress, eventually during technology of its production.
