Corrosion- and creep-resistant materials

Course guarantor:

Jakub Horváth

Lecturer:

Jakub Horváth, Jiří Janovec

Tutor:

Jakub Horváth, Jiří Janovec

Supervisor:

Department of Materials Engineering

Synopsis:

The lectures deals with the mechanisms of degradation from the point of view of corrosion attack and the influence of the combination of increased temperature and mechanical stress, and subsequently through the characteristics of material properties with specific materials applicable to the given area of degradation.

Requirements:

Submission of tasks from exercises in appropriate quality.

Passing the final test
