| Learning Outcome: | Students will gain an in-depth knowledge of the fundamentals of hot forming of metallic materials and the microstructure evolution during hot forming. They will learn about the main defects that occur during different thermomechanical processes and how to mitigate their formation. They will also learn how to apply the Dynamic Materials Model to evaluate the hot formability of various metals and alloys. The thermo-mechanical treatment of different types of steels will be reviewed, giving students further knowledge of forming and deformation of steels in different applications, e.g. car body and pipeline applications. |
