The course covers the materials which are used in the automotive industry for the car-body, the chassis and the powertrain, with special focus on those components that have the greatest influence on the total car weight and on those materials that can be used for the purpose of lightweight design.
Within this scope, the course intends to provide a more advanced and complementary knowledge, with respect to the basic knowledge offered by the B.Sc. level courses of the Italian Universities.
The course especially emphasizes the understanding of the interdependency between the choice of the material, the design of its production cycle (including thermal and mechanical treatments), the material structure and microstructure and its evolution during the production cycle, and the final service properties.
