Prerequisites:

Basic knowledge of machining, forming, foundry and welding technologies.
Course contents:

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). Further technological properties of non-metallic materials.
Teaching methods and criteria:
 
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.
Checking the knowledge, skills and abilities gained after the completion of individual thematic areas (protocol checking, written test, etc.).
Controlled participation in lessons:
 
Type of course unit:
    Lecture  13 × 2 hrs. optionally                  
    Laboratory exercise  13 × 1 hrs. compulsory                  
Course curriculum:
    Lecture

Lectures
Machinability 
1. Definitions, decisive factors, criteria and standards of machinability
2. Groups and classes of machinability of engineering materials
3. Cutting as a dynamic process of hardening and de-hardening; dynamic recrystallization.
Plastic flow in material under high strain rate. Interaction between workpiece and tool materials

Castability 
4. Physical properties of the molten metals and alloys, surface tension of liquids, measurement of surface tension, influence of chemical composition of metal and temperature to the surface tension of melts.
5. Ideal and real liquid, fluid flow, turbulence in fluid flow, viscosity of molten metals and alloys, losses during fluid flow.
6. Wettability of casting molds, thermal accumulation of casting molds, penetration of metals and alloys, fluidity of melts, fludity tests, volume changes of metals and alloys during solidification.

Formability 
7. Physical essence of plastic deformation and hardening. Formability of metals and alloys
8. Theory of plastic deformations and principles of metal-forming
9. Conditions for the appearance of plastic deformation, analysis of deformation processes.

Weldability
