Learning outcomes of the course unit

The student gains basic information concerning structure, mechanical properties, and applications of advanced materials in recent engineering and technology.

Prerequisites

Solid State Physics, Materials Science and Engineering.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.

Assesment methods and criteria linked to learning outcomes

The assessment of a student is made upon his performance in practice and quality of a discussion on topics selected at the colloquium (lecture notes allowed at preparation).

Course curriculum

Work placements

Not applicable.

Aims

The main aim lies in elucidation of unique microstructure of advanced materials as well as in understanding a physical nature of relationship between the microstructure and mechanical properties of such materials. The student also gains basic information about possibilities of application of these materials in the recent engineering practice.

Specification of controlled education, way of implementation and compensation for absences

The presence of students at practice is obligatory and is monitored by a tutor. The way how to compensate missed practice lessons will be decided by a tutor depending on the range and content of the missed lessons.
