    The goalStudents will broaden their knowledge on changes of microstructure during phase transformations and 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.
    The outcomeNew knowledge on mechanisms that lead to changes in microstructure and determines final properties. This subject is fundamental knowledge for all metal forming and thermomechanical processes technolgies. ;
