Course detail

Technological Properties of Materials

FSI-WTVAcad. year: 2011/2012

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.

Prerequisites

BUM, 3SV - general foundation
2VT, WTC - technological foundation

Co-requisites

Not applicable.

Planned learning activities and teaching methods

The course forms part of the Materials Sciences and Engineering study programme. It is given in the winter semester of the 1st year follow-up MSc studies, spread over 13 weeks, offering 2 weekly hours of lectures and no exercises. The lectures are given on the basis of contact with students, using PowerPoint presentations prepared by individual lecturers. They are complemented with extra assignments (inclusive of problem solving) based on recommended literature.

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.
