Institute of Materials Science and Engineering

The study of the experimental methods used in the structure analysis (morphology and phase composition) of materials requires the basic knowledge of physics and mathematics on the level offered in the course of bachelor studies, and also knowledge of materials science and engineering – on the level of BSc at the least.

Exam: written and oral parts.
Awarding the course-unit credit is full and active participation in exercises and credit test.

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

The course aims to provide students with an overview and fundamental theoretical principles of the most common methods used for complex engineering materials structural and phase analyzes in current engineering practice (physical principles of the methods, instrument parameters, application scope of the methods, etc.), inclusive of specimen preparation.
The knowledge of the principles and application potentials of the basic methods of structure and phase analysis, inclusive of procedures of taking and preparing specimens. Separate evaluation of structure components for all the kinds of materials under study, and assessment of the relations between the production technology, structure, and useful properties of materials.
