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.

Modalità di esame: Prova scritta in aula tramite PC con l'utilizzo della piattaforma di ateneo;
Exam: Computer-based written test in class using POLITO platform;
Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.
Exam: Computer-based written test in class using POLITO platform;
The exam aims to ascertain the knowledge and understanding of all the topics covered in the teaching and of their interrelationships. The exam is written and includes 10 open questions requiring short answers (about two lines each), which in total have a weight of 2/3 of the final vote, and 1 topic, requiring an extended answer (about one page), which have a weight of 1/3. The duration of the exam is 1 hour. All the answers will be evaluated on the basis of correctness (in respect to the state of the art) and completeness (in respect to the topics covered in the teaching). Textbooks, lecture notes, formularies, and electronic devices cannot be used during the exam.
In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
