Not applicable.

Students will prepare metallographic samples for all evaluation methods, and evaluate structural components. They will be made familiar with the use of particular metallographic methods. They will be able to evaluate independently the relations among the technology, structure and utility properties of the material.

Students are expected to have general knowledge and basic knowledge of mathematics, physics and chemistry acquired at secondary school. They should have the basic knowledge with respect to the following fields of materials: the structure of metals and alloys, composite materials, constructional ceramics and materials for electronics.

Not applicable.

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.

Course-unit credit is conditional on attendance at all lessons. Final grade reflects the result achieved in a written test where a student has to answer three questions; two theoretical and one practical.

Not applicable.

Not applicable.

Students will be made familiar with the basic practical methods of the structure imaging, qualitative and quantitative evaluation of the structure. Students will observe and evaluate materials as needed for their diploma theses.

Attendance at seminars is compulsory. Absence from seminars may be compensated for by the agreement with the teacher.
