| The goal | Students will acquire knowledge on changes of microstructure during thermomechanical processing and its influence on mechanical properties, which is basis for understanding the relationship between chemical composition, thermomechanical processing, structure and properties in metallic materials. Physical basis of fracture and ddifferent fracture mechanisms are aslo explained.. | |||
| The outcome | Knowledge on mechanisms that lead to changes in microstructure and determines final properties. This subject is fundamental knowwledge for all metal forming and thermomechanical processes technolgies. | |||
