| The goal | To acquire knowledge on changes of microstructure during thermomechanical processing and its influence on mechanical properties, which is basis for understanding the relationship between thermomechanical processing, structure and mechanical properties of metallic materials. Basic knowledge on fracture mechanisms in metallic materials. | |||
| The outcome | Knowledge on interdependence of composition, structure and mechanical properties of metals and alloys, as a fundamental knowledge for thermomechanical processing technologies and materials selection. | |||
