Course detail

Technological Properties of Materials

FSI-WTVAcad. year: 2019/2020

Technological properties of materials explained, in particular, on the basis of materials problematic. The technological properties included concern metallic materials (castability, formability, weldability, and machinability). Technological properties of non-metallic materials are incorporated in courses dealing with them.

Learning outcomes of the course unit

Knowledge and skills in the area of assessing, affecting, and applying the basic technological properties of metals and alloys, preferably with the materials viewpoint being applied. Capability for creative work or cooperation in the area of the given manufacturing technology.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is suplemented by practical laboratory work.

Assesment methods and criteria linked to learning outcomes

Semestral examination (written exam covering the whole scope of the given problematic). Assessment based on ECTS criteria.

Language of instruction
